I have a pretty stable setup now. I mainly focus on TV and Movies but I have the following:
Plex for streaming
Overseerer for media requests
Radarr and Sonarr for Movie and TV acquisition
Jackett for indexers
Gluetun for vpn
From there I basically let radarr and sonarr handle the organizing for the most part. I have a movies folder and a TV folder in my NAS that they save to. I really only have to go in and clean things up every few months or so.
Unregistered torrents (from upgrades to season packs or nuked releases) and the occasional upgrade paths that don't always work.
My own upgrade paths tend to pull in some versions which get made redundant so every so often, just ensuring there's no multiple copies as a result of said upgrades
