Piggybacking on a reply to this comment, if you want to go an alternative (or additive) route of Usenet you can look to add NZBGet (or SABnzbd) with NZBHydra to manage Usenet downloading and indexer search respectively.
In respect to this my setup for this (on Docker) looks like: radarr, sonarr, nzbget and nzbhydra. I serve my media using Plex (there are a lot of great alternatives to Plex out there also but I'm still very happy with Plex even as a non-paid user).
