The usual go to for self hosted password managers is VaultWarden. There’s no deb or rpm package but you can get it spun up with docker pretty easily. Any reason you’re specifically looking for “included” or packaged solutions? That’s going to severely limit your options.
Everything else just makes it easier to manage which depending on your preferences and how much content you’re dealing with that may not be a problem for you. I run the whole stack using Deluge as my downloader with a VPN. Radarr, Sonarr, and Lidarr automatically locate the torrents on the public tracker sites for me, send the downloads to Deluge, and imports the media into Jellyfin when the download finishes. I also use Jellyseer for discovering and requesting content, as well as allowing family members to request content. I also use Prowlarr to manage the trackers being used in the various arr apps. It’s a very robust and automated system but it all boils down to just downloading torrents over a VPN.
