I really don’t have a use case for specialized stuff like jellyfin or vaultwarden.

Idk about vaultwarden, but Jellyfin is just a media server. Sonarr/Prowler lets me queue up the shows I want to watch. Jellyfin plays them on the two big TVs and the kid's pad I have in the house. It's pretty straightfoward. Less tedious than fishing for torrents on the traditional basket of sites and manually queuing up the downloads. And I can watch the shows anywhere, rather than being anchored to a single machine.
