Honestly, a lot of it is what I used to watch on YouTube. Pretty much anything from Sam @ Wendover Productions (including Half as Interesting, Jet Lag, and some of his Nebula exclusive series such as Extremities), Practical Engineering, Pinely, Chubbyemu, Bright Sun Films/Travels, stuff like that. Day Pass is an exclusive that comes to mind.
Sometimes Nebula uploads have extras even if they upload to both YT and Nebula. I like Nebula because it allows me to get away from Google while still supporting the creators I like from there. It's pretty cheap, all things considered.
I do the same with William Osman's Sauce+ (based on floatplane but for engineer creators).
