Go for the Arr suite. Radarr for movies, Sonarr for series. They work well with Jackett, and actually have an even better (use comfort) alternative to it called Prowlarr. Once set up, maybe spending a couple hours understanding how they work, downloading a movie or a series is as easy as entering its name in a search field, seeing the related list (completely accurate), hitting add and watching the torrent start automatically. And if Jellyfin is configured as well, I can start watching whatever I downloaded with a couple clicks right away on any device I have Jellyfin, in full whichever quality my pre-set profile searched the torrent sites for. That’s quite the supply chain, centralized after landing on your host computer, streamable to any local devices or online devices, and can be automated to even search and download queries that come through discord messages.

Understanding the indexer stuff can take a little time at the start, but it is actually as easy as saying that Jackett/Prowlarr is just the middleman between you typing your movie name and searching through all torrent sites you want at the same time. The net has videos of using them if they look confusing at any point. Using Radarr/Sonarr themselves after setting up the indexers is as straightforward as using any streaming services.
