Good book/TV/movie trackers à la Goodreads

As part of the ongoing quest to turn everything I enjoy into an exercise in statistical modelling, I had a look around today for a way to track what books I've read and which ones I may be interested in. I found a bit of a jumble of things in various states of development, half of which are owned by Amazon (which I'd prefer to avoid) and the other half with incomplete, confusing, and opaquely sourced data.

I use this kind of service for a handful of other topics, mainly untappd, AniList, and last.fm. I'm only really interested in the ability to keep track of read/watched items - I don't find myself rating things or making complex lists unless I started my journey with a hobby by using one of these systems. Of course for this to work out, it needs to have a fairly comprehensive library. I was unfortunately disappointed with OpenLibrary, which would otherwise be my top pick. I found systems like readarr and calibre a little clunky for this in the past since they're so focused on file management, but I'm open to retrying them.

Does anyone here have any insights in this space? Not just limited to books, I'm also interested in trackers for TV/Movies. Preferably not owned by a massive company like Amazon, I know a lot of people were disappointed when they deprecated the Goodreads API.
