Here is an interesting discussion on the 28mm vis-Γ -vis 35mm lens for documentary photography:
Focal Length Feud: 28mm vs 35mm for Telling a story β by David Babaian and Simon King
https://emulsive.org/articles/focal-length-feud-28-35
I have used both and at the end of the day it seems to me that either will work well, if you are willing to fine tune your shooting technique for each lens.
Thoughts?
