Plex has worked well for me for many years with the lifetime pass. Got it 10 years ago so it translates back to about 8 euro per year.

That’s not a bad deal.

Something with trans in there? That should not even come up in his mind.

I would say fedora silverblue. Have been using it for a while. All updates, app and os, are distributed via app center so reasonably foolproof.

And a benefit is that it has podman out of the box so you can run docker images without fiddling with the terminal.
