Unraid would be a very good choice for someone who is reaching out and asking this question. Debian can do the same but I suspect it’ll be easier to setup and manage on unraid.

Disk management in unraid is also great.

Why not just use a graph database?

Jellyfin is easy enough to get going, and I have it my annual try but it still feels clunky. Compared to Plex the windows client just doesn’t feel up to the level where Plex is.

Also noticed in my 5 minute attempt that hdr support seems to be lacking still.

Love the idea of an open source media system but it has a long way to go still.
