I use Chromecast with android TV, it's about perfect with jellyfin, and if I were to domit again I'd probably spend the little extra for the 4k model even though my TV is 1080p (more horsepower). You can run a different homescreen to somewhat degoogle it.

Probably not what you're looking for given what you've lined up here, but I live and breathe with it every day and it's great, and as an added benefit you can cast from a lot of services or websites as well.
