I was about to post my arr suite until i read your last line :D For recommendations i follow some youtube critics (like stories of old, mubi) who regularly provide recommendations and my tastes match with theirs. Then there’s reddit/lemmy movie forums. And i just use QBittorrents in built search to just download if i’m not tracking the movie/tv on my arr stack. And for playback locally i use mpv. I tried streaming services a long time ago but they are incredibly inconvenient compared to how flexible it is to watch/find something on torrents and the quality is also better.
This was one of my main needs when i started to look for a platform on the fediverse, while wordpress was the closest thing to what i needed it had partial support for federation but thankfully a little known gem called ‘hubzilla’ turned out to be exactly what i needed to set up my digital home.
