My absolute favorite is primitive technology. I can turn that on and just lose hours. No dialogue, marginal sound effects.

blacktail studio has a secondary channel with long cuts with no commentary.

a lot of the turning (lathe) channels are no-talk.

MyMechanics is a channel about restoration and machining. No dialogue and extremely satisfying to watch

Hard to get much better than Adam Savage and the Tested crew https://www.youtube.com/@tested

Adam does long from videos of tons of stuff he builds. I find his build videos to be very zen.

I strongly recommend Epic Upcycling although the table saw noise can be jarring, AT Restorations and byOldHand. Edited to add: New Yorkshire Workshop makes a lot of cool projects, and you can also follow his journey to restore a Victorian house with proper aesthetics and techniques.
