YunoHost is pretty much alive than ever, but don’t expect it to be up-to-date all the time since their way of doing stuff is pretty extreme to maintain.
So my advice would be, spend enough time with it, and when you get the grips move to docker containers.
I just plugged it to my TV to remote play GoW on a big screen.
No other device can pull this off with 4k Stream, HDR, Surround Sound, full DualSense support and sub-1 frame (of 60) latency.
