As others have mentioned, the blahaj.zone Sharkey might be what you want, but I’ll give a couple pointers in case you want something else (or someone reading this does).

You can join any fediverse instance as they are mostly compatible with each other. Join a small instance with good moderation based on what you like. It might not be easy to decide what the best instance for you is, which is kinda a downside of the fediverse, but look around. I joined floss.social because I’m a programmer, they have a user cap, and their moderation is great. While I don’t browse local posts much, it’s good to see fellow people with similar interests posting about things I like, all with no algorithm.
