I can recommend Dr. Becky's introduction to the issues surrounding the Hubble Tension and recent JWST measurements in this 16 minute clip, as she introduces laymen to the problems well: https://www.youtube.com/watch?v=hps-HfpL1vc
It's an older clip, but it checks out... ;) (still JWST discoveries and she most importantly introduces the viewer to the still remaining conflicts)
