If I was starting new today I’d go for Jellyfin but my family is all set up for Plex now and I’m not going through that painful process again :D

In this case you’d be better off on Facebook and Reddit looking for local services that can help you.

You could keep the chain going and pass it down to somebody else?

If you have any old hardware/laptop laying around then use that until you nail down what you actually want to do and need.

I would start by adding a couple more indexers but don’t go overboard. 3 or 4 should be good and then swap them out as needed. Also something to note is make sure you aren’t just “hit n run” on everything and seed properly.
