What I listed aren't just customary ways of doing things, they're objectively bad UX patterns.

Forcing 3 different horizontal bars on a screen that is wider than it is long needs a reason and justification to be there, one that MacOS does not have in the face of Windows' simplified yet more useful layout.

I used Windows most of my life but have used MacOS day in day out for the past several years for work, and it's worse at its main job of actually managing your day to day applications.

Windows has actually improved enormously over the past 5-10 years in terms of window management, with snapping, powertoys, rock solid multimonitor support that always remembers which apps should be where etc. Like I said, people are just caught up by their reputations, if you use both on a day to day basis there's no way you'll find MacOS more convenient.

Edit: though in the spirit of concession I will concede that I've come to prefer MacOS's ctrl+space to search, and prefer enter to rename a file instead of f2, however, the former at least can be added to windows with power toys.
