When I've led teams, I've never enforced things like indentation or bracketing styles. Things I do enforce are (1) explain complicated code with comments, (2) make it readable (for whatever definition of readable), and (3) reasonable naming conventions (i.e., don't name every variable i, j, k). These guidelines are useless for automated tooling. Perhaps in the age of LLMs this will change (who knows).
I've found the strict requirements and automated tooling absolutely terrible. I often align things to keep parallel structure to show how different lines are the same or to create 'tables', etc. Formatting tools destroy this. For me, using my emacs rectangular editing, the alignment greatly increases productivity. This is one example. I'm much faster at editing personal projects / projects I've led than ones with strict style guidelines.
For me, I always tell my guys: edit in the style in which you are fastest and most efficient. I believe this greatly increases productivity rather than having a team 'nosy neighbor' that cares whether you use two or four spaces for indentation.
My two cents.
