Well I mean if they want a home server they will have to learn something.

Personally I just set my friends and family up with a stremio/torrentio/real-debrid setup. Nothing to host, I just pre-configure Stremio for them. Then they can just login on any device and it’s good to go.

Make them an unraid usb and then they can just stick in a spare pc and they should be good to go. Then they can use the gui to download and install docker images. Would be the path of least resistance IMO.
