I wasn't going to reply, but when I thought about it, you can install wayland on top of linux.
The kind of benefit you're getting out of this is better driver support (from the kernel) & less resource usage (lightweight distro + wayland on background = 2GB~ish ram usage).
Also it'd be easier to get Gapps running (if you need it) on waydroid rather than rooting lineageOS TV to do so.
I tried it once & it was more than enough for light gaming, IDK about plex but hardware acceleration is supported since there's no VM tech utilized (nividia isn't supported tho).
Most linux distros with wayland should be enough, but check Wayland install page just to be sure it's well supported (by distro), I see void-linux & ether configured labwc or KDE plasma should fit your needs better.
