I haven’t used an ARM system, but docker might be the best bet? Get docker installed and find instructions for install Jellyfin and each arr program.

Use Android TV with an alternate launcher like FLaunchee

For FOSS it’s Flauncher for me. I haven’t tried any others, I like Flauncher because i could put big simple app icons on the screen.

If you’re going through all that work, try an alternate launcher.
