I'm not doing links because I'm lazy, but I watch a lot of YouTube and these are my favorites:

Ordinary Things - funny smarmy British dude explains ordinary things. Once a month or so, very high effort stuff.

That Chapter - funny sarcastic Irish guy explains true crime things. Twice a week on a good week. Also high effort research

Internet Comment Etiquette - this is not for you. Don't watch it. You've been warned.

LGR - the best legacy youtuber talks about the best legacy tech.

Patrick Willems - funny American guy explains movie stuff.

The Crafsman Steady Craftin - funny puppet man does crafts. This is the most high effort channel on YouTube.
