In my opinion, you should be running everything as a docker container. I would first get Plex running to learn, and expand from there; Sonarr, Radarr, Prowlarr, Overseerr, torrent client, etc.
For resources and documentation, Spaceinvaderone on YouTube is great (older but still relevant), and I also enjoy IBRACORP’s videos. As for text based, TRaSH Guides are basically defacto.
Amazon?
