Mostly short form explainers about interesting subjects, presented in a sort of breathless British TV presenter style. Like a young Attenborough but less posh. Pretty good channel.

Hard to pin Down. Most of his stuff is going to unique and unusual places and customs and why they end up like that. But he also does some pretty great videos on linguistics and computer science.

I would say the best to describe his content is that he is a journalist doing those old school "general interest" style news stories.

My best answer would be for you to go to his YouTube channel, find a video that even mildly piques your interest, and watch him. Like the other person said, he's hard to pin down because he doesn't cover one specific field of interest, but he does make sure to research everything he's talking about. He can even make talking about poorly designed road intersections interesting.

You know those shows that your parents might've had you watch as a kid that were about exploring and learning about new places? Basically that for adults
