For myself I personally find YouTube (long form not shorts) actually does a good job of recommending me content that is relevant to my interests and generally doesn't shows me low quality content way outside my interests. Possibly the worst in this regard is Reddit which seems like it is constantly mixing in "engaging" content.
My wife uses TikTok and I'm generally surprised how focused her recommended content seems to be, however she has been using it for a while now.
I'm interested in people's personal experiences!
