My parents are getting a new tv, and are asking for recommendation. I think all I can influence is the brand/model (not realistic to propose rpi and more complex systems). I instinctively avoid google/android and lean towards anything else open source, so probably LG WebOS.. But I had bad luck searching for more detailed comparisons. Maybe you have experience or opinions?
LG WebOS doesn't have good support for things like Jellyfin. If you want to ever build a library of media and let them have easy access to it, then WebOS is gonna suck, so will Samsung's Tizen. But all the Android TVs have access.
Don't know if you're interested in that kind of thing, but figured I'd share it in case it was a factor.
The only other alternative is a commercial display.
This is untrue. You can use Jellyfin or Kodi natively on LG WebOS on the TV and stream whatever you want locally. You have to grab it from the homebrew channel or sideload it. It's a little bit of a process though. Nothing crazy. But it works!
Edit: you can also get YouTube without ads off Homebrew.
Yeah, sideloading it requires getting a development code from the company, jailbreaking your machine, then installing a full development environment...
Not what I'd call user friendly.
Meanwhile, on something like the FireTV stick, if someone gives me the URL to an APK, I can install it.
Rooting (assume you meant this by jailbreak8ng) is not required for this process. Only some apps reauire root. Kodi and the youtube adfree apps don't require root.
