Pretty good explanation dude!
Overseerr is for Plex, and fuck paying for piracy, so I use jelly.
I mostly use Jellyfin to, but you only have to pay for Plex Pass if you want to "unlock" HW transcoding with Plex Pass.
You can just use regular Plex to forward the request to Overseer, all you have to do is just add the tvshow / movie to Plex's Watchlist. The Plex app is available for every device out there while Overseer is only a selfhosted webapp. Like for my parents, i just sent them up Plex on their AndroidTV device and they can request whatever the fuck they want from Plex Discover, then switch to Jellyfin to actually watch it, cause Jellyfin support HW transcoding out of the box. My $120 Intel N100 mini PC can GPU transcode several streams at once while using like 4watts total.
Radarr does movies. Sonarr does TV. Sonarr does TV. These programs then schedule a download when it gets released, or if it's already released, they pass the request down into Prowlarr.
Yeah an example for context: I currently Shogun (2024) added in Sonarr. Sonarr fetches the media info from sites like IMDB, etc and knows how many seasons, episodes, names, and release dates are. If its in the future, It will query Prowlarr at that date ( which is already set to use certain torrent sites,, i use private ones) on a set interval until it finds it based on your search criteria, such as 4K quality) download it / unpack it if needed / move it to your media folders, which are nicely name by Sonarr.
You also download everything to a seedbox and have it securily puss the download to you. Or you can run everything on the seedbox. Most of them have n00b friendly one click install for all the *Arr suite and more, like Ultra.cc.
