For each Ubuntu LTS release, Canonical maintains the Base Packages and provides security updates, including kernel livepatching, for a period of ten years.
Installing Debian is not an alternative to the 10-12 year Ubuntu LTS support because Debian doesn't offer that kind of support. Also as the sibling noted, Ubuntu Pro isn't needed to get the same support you're getting from Debian. Ubuntu Pro provides additional support that you don't get from Debian throughout the support lifespan.
BTW, not offering 10-12 years of support is totally reasonable for a community distribution. I don't expect volunteers to be backporting fixes for packages built 12 years ago.
10-12 years of support attract only those who think they will never need to update. I don't think so and I update to each released version, each ~2 years. I know that skipping a release is not supported in any distribution. And update cost grows exponentially over time. So thank you, but I don't need a support for longer than 3 or 4 years. But for that period I want to have security updates for all software I installed, not only "base". And I want to get them from public repositories hosted on independent mirrors to be sure that I wont be banned by vendor for some reason.
As for additional support, I don't need it. I can solve my problems myself and do if faster than Canonical would do. And not only my problems. I also contribute to open source software and I want my contributions to be available to anyone, not only those who pay for support to some company that I have no relationship with.
There's no need to register an account with Ubuntu at all. You have no idea what you're talking about. You don't need a pro license to get updates for an LTS for 5 years of support. The "base packages" are both the "main" and "restricted" repositories - it isn't just a few "core libraries" as you seem to think.
Debian is an excellent distro but I can't even find out what Debian considers to be covered by their LTS. Their page about it is very vague. I would guess that it's the same though - "main" repository is what they cover. Similar to Ubuntu.

From what I read, the +5 yrs with a Pro account is on top of the LTS 5 yrs support.
Say Xenial ended last April 2021. With Pro that extends it another 5yrs. With it support ends some time in 2026?
But that is not +5 from when you got the Pro account. It started ticking the moment Xenial EOL'd. So if I signed up Pro now, my Xenial updates will still end on 2026. Should work for later LTS versions, +5 after base 5 on the same Pro account free up to 5 machines.

Really? So why does apt tell me that I need to get updates for more packages than it has downloaded each time I run apt update? I have latest LTS (22.04) on my laptop. Maybe you have no idea what you are talking about? I could get any updates until recent (year or two? I use that laptop only occasionally, so I don't remember the exact time), but now it is clear that Canonical goes the same way as RedHat/IBM.

You are wrong because Debian's main is not similar to Ubuntu. Debian has no universe repo, all FOSS packages go to main.
