I think you might like Threads! It does show you random posts, based on your likes, and it has really good functionality for banning, blocking content you don't want. You can also add, via Instagram, words you want excluded. I have a feeling it's a bit like TikTok, where it just gets better in its recommendations the more you use it.

Substack is another one I think you might like. Very similar to Medium except it's turning more into a social media site, with loads of chatter and Twitter-like posts ("Notes").
