Any specific channels?
and Pilot Debrief https://www.youtube.com/@pilot-debrief/videos
both are experienced, detailed, serious, sober minded
If you start out with those two channels but also pay attention to youtube's suggestions for related videos, you'll get a good selection.

I like his tone and he's technical like blancolirio.
I also found this video on CFIT in General Aviation to be quite compelling https://www.youtube.com/watch?v=8PBUVMCbmFQ

The former is more into the science of air safety, they do case studies of crashes as well as go over technique, pitfalls, and pilot psychology. The latter is an active airline pilot, similar to mentourPilot just with a less refined and more relatable (to me at least) style. He does "reaction videos" - but in a good way - where he analyzes aircraft incidents from a perspective of a commercial pilot. And he regularly debunks ticktock misinformation.
