Not new, but some non-fiction Youtuber's I've love watching since W2R mentioned that. These are a tiny slice of all the channels I'm subscribed to, YouTube is an amazing fountain of good content these days:
Legal Eagle (lawyer does law related videos)
Tom Scott (general interest)
Veritasium (science education)
Smarter Every Day (engineering oriented, but he does process stuff too)
Filmjoy (Movies with Mikey) if you like film analysis
Megaprojects - Lots of military plane stories, but also buildings, space stations, giant dams, etc.
Jill Bearup - Media review/criticism mostly focused on stage combat these days (which is really fun)
Spencer Cornelia - Fake Gurus, celebrity financial failure, starting FIRE journey, etc.
Wendover Productions - Process engineering type videos (how things, work about airlines, transportation industry, etc).
Economics Explained - Australian Economist analyzes countries, current economic events/trends, etc.
How Money Works - about economic topics
Xyla Foxlin - adorable engineer makes cool stuff (hand made canoe, a xmas tree rocket, etc)
The B1M - Real estate/building big projects
TwoSetViolin - a pair of former professional violinists who gave up their orchestra positions and went full time youtube who get amazing performers to come participate in their shows. Ling Ling workouts with some of the best violinists in the world are really amazing.
PBS Space Time - who doesn't love physics?
CGP Grey - used to be awesome, but new episodes are rare now, go watch the backlog they are fun
Kurzgeasgt - Science (astrophysics, social science, medical, etc) education in awesome animated format, really fun, well written and interesting.
