There i think that's it. That's a ton of stuff but I really follow more quality YouTube than anything else and I like sharing great YouTube channels. If you enjoy interesting YouTube I would honestly just check a couple of these out and see if the topics fit your interests.
These channels range from science, space, physics, to history, sports, cars, to tech, movies, games, to makers who build stuff seriously as well as builders who make stuff silly.
Not everything here is video essay, but it's high quality content imo
