I'm honestly very happy with Fediverse platforms like Mastodon and Lemmy.
The ample amount of servers to join I think scares off the worst people coming from platforms like Twitter and Instagram who only post random bs 99% of the time, and can't be bothered to take a couple extra minutes at most to understand how Fediverse services are different from traditional social media let alone poke around to find an instance that suits them. In that way, it acts as a filter.
(I don't mean to sound elitist, but I think all social media would be a lot better if people wanted to have enlightened discussions about things going on in the world, for example, instead of posting heavily edited photos of themselves or dancing in front of a camera. Is that really peak internet?)
What's left are more thoughtful people that genuinely care about the mission of Fediverse platforms (like how lack of a profit incentive means there isn't an incentive structure that leads to the enshitification of platforms), or at the very least took the time to understand how it works.
Now the only platform left to conquer is YouTube.
