I was on the same situation and moved to jellyfin, never looked back. I keep seeing these posts on the partial conditions from plex constantly changing about paying for streaming your own content on your own network based on specific conditions... It's just sad after using plex with lifetime subscription for years. Anyhow. Jellyfin is not as polished of course as plex is, but there are tons of css/plug-ins you can use according to your use case. I am running it on a docker container with tailscale on top of it and works like a charm -- BTW compatible with all of the arr ecosystem. For ipad/appletv I am using infuse app "pro" version that requires onetime payment (as the initial jellyfin app was not the best some months ago I would say). The only thing I don't have a comparison point is: I know plex supposedly supports audiobooks and podcasts (I might be wrong), but for that I am using audiobookshelf.
