I've been pretty happy with my Pixel Tablet running GrapheneOS. I don't know everything you're hoping to do, so maybe Android won't work for you. However, I've been using Plex, Newpipe, Termux, Roon, and other apps, and it's working well for me.
The stand still works as a speaker when connected as well, which is nice.
I mean...you can kill him once you take him out of the story.
