I've happily been a Fedora user for many years now, but RHEL's recent choice to put their source code behind a paywall has me pondering ethical considerations of my distro choice.
It's my understanding that this doesn't have a direct impact on Fedora, and I feel confident that it will continue to be a great distro for the foreseeable future, but I want the commercial/enterprise/corporate influence on the distro I run to be as minimal as possible. For it to be as free as possible.
With that in mind, what distros would everyone recommend?
I only have recent-ish experience with Fedora, Debian, Arch, and Ubuntu. I don't really know much about any others.
Ideally, I'd like it to fit within these boxes as well:
Reasonable release cycle time. Debian as an example tends to be too stale by it's nature. Edit for clarification: doesn't have to be bleeding edge, just don't want to fight with outdated dependencies if I'm compiling something from source. I feel distros generally ride this line well, but I've run into a handful of times in the past with Debian.
Doesn't try too hard to be user friendly. Obsfucating system internals, forcing a specific DE on you, that kind of thing.
Not overly time consuming to maintain. Arch would be an example of that in my opinion. Don't get me wrong, Arch is awesome. But maintaining a rolling release and a bunch of AUR's gets tiresome.
Doesn't try to force you to use a flatpaks, snaps, etc.
Seeing it all written out, that's pretty picky. And maybe this unicorn distro doesn't exist. But on the other hand, maybe it does.
A final thought. I know Debian has a testing branch. Anyone have any experience using that as a daily driver? Is it viable?
openSUSE also has sponsors other than just SUSE. They have a very good and close relationship with SUSE, but it is also somewhat different than Fedora.
Mint is based on Ubuntu LTS. IMO it's fine for gaming since you can use Liquorix or an Ubuntu OEM kernel plus the kisak-mesa PPA to keep more up-to-date, but seeing as how OP wants to be close-ish to the latest and greatest, only upgrading wvery 2 years is probably too slow for them.

I've used Debian testing (bullseye at the time) before and it was a pretty pleasant experience. I like how much control I had over it compared to Ubuntu at least.
With that in mind, what distros would everyone recommend?
I like Arch and I don't have much trouble maintaining it. It's just a yay every now and then. The only issues I've had were upstream packages introducing drastic changes like when Nerd Fonts changed their naming scheme so I had to fix my ~/.Xresources manually. I use i3wm so it might not be an issue if you use some popular DE like Gnome and KDE.
Have you looked into OpenSuse's Tumbleweed or Leap? They might fit the bill, but I don't have much experience using either.
I've used Debian Testing on workstations for years, it's great! Sure sometime security patches come in a little later, but it's generally not an issue.
I'd recommend Mint, because, from my experience, it's pretty stable, UX is designed so terminal usage can be kept to a minimum (but you can still prioritize it if you want), support from programs is overall good, and it ditches snap. But worth noting that, if you need cutting edge features, Mint is not for you, as it seems to be the new Debian, where updates are traded off for stability.
I'm using EndeavourOS on one PC, and Pop_OS! on another. After a bunch of distrohopping (pure arch, manjaro, Linux mint, fedora, etc.), these are the two I like the most and have decided to settle for (for now at least lol).
Your second, third and fourth points eliminate many distros such as Ubuntu. And many of the distros out there are based on Debian.
Debian isn't really stale. It is currently running kernel 6.1.10 which is not a long way from 6.1.39 (longterm, and that only came out 2 days ago). Stable gets constant updates. Testing is also generally very stable. The only thing that stops testing moving into stable is what are considered Release Critical bug count. All documented here: https://www.debian.org/doc/manuals/debian-faq/ftparchives#testing
Also while Debian 12 is LTS, it won't stop 13 from coming out and it doesn't stop you from upgrading to 13 (although you may lose LTS if they decide that 13 will not be LTS).
Debian is about as open as you can get, certainly does not infringe on your 2, 3 and 4th points.
Only other thing is what you are doing with your Linux, this might make a difference (you say daily driver, but doing what? Just office stuff, or heavy video editing, etc)
My go-to distros are Pop os for better game and new hardware support, and Linux Mint if I'm wanting something a little more stable. Both have served me really well over the years.
I've been playing around with Siduction (basically Debian unstable) recently and that seems pretty decent if you want the latest and greatest.
Mint has been pretty good for me. They didn't follow along with Ubuntu and snap everything, but if you don't want to touch anything Ubuntu there's a version based on debian directly.
OpenMandriva recently released a rolling release version of their distro. It's a small project, but I'm personally looking at it as an alternative for Fedora.
It's been a few years since I last used Sid, but I don't remember it being that unstable. I've never spent much time with Arch to make that comparison though, so I can't really judge on that.
Another Debian Testing user here, I've been running it for I-can't-remember-how-long and genuinely can't recall the last time there was a showstopper. My use case is very standard though, no gaming or running servers or heavy development. Recently rolled up to Trixie with no issues whatsoever
I'm sure the arch people will be here soon to say snarky things, but...
I've used Manjaro (stable) on my desktop for about 5 years and have no reason to leave. Updates are about once a month, other than security patches to browsers that for zero-days. It's still arch at it's core, but it's less upkeep.
Maybe I don't know what I'm missing, but I feel like I'm in a pretty similar situation as you.
Manjaro has been absolutely lovely for me as well. The only breaking updates for the past few years were because of the bugdie desktop, but fault seems to be with budgie.
When it comes to Debian, you might find yourself getting more up-to-date software with the backports repo, particularly when it comes to the kernel. It's not a large selection of packages, but there's some useful stuff in there.
You can also use apt pinning, but that requires maintenance and makes it fairly easy to break everything.
Good idea might be to keep Timeshift on a decent schedule and if you mess something up, run through an older snapshot.
Alternatively, OpenSUSE Tumbleweed is a good rolling release that has full integration with btrfs, so mess up an update and just boot into an old snapshot. Can also choose any DE (that's in their repos, at least) on installation. It doesn't require much maintenance at all. Very unlikely to break regardless.
OpenSUSE Leap seems to be your best choice. It does not have the time consumption of being rolling release, but has a good release cadence. It is also an RPM distro, that should make things feel at least a little bit more familiar.
I've been using RebornOS, which is an arch based distro. I think it fits what you want perfectly. It's a rolling release and has heaps of customisability and nothing is forced on you.
