I agree with most of your points, save for alt-tab. macOS app and window management is completely different from Windows, and trying to use it like Windows only ends up hurting.

Minimizing a window in macOS takes it out of the working set. You can't quick switch to a minimized window, and it doesn't even show on Mission Control. You have to click the minimized window in the dock to bring it back. In short, minimizing a window is not just a visibility setting, but a workflow choice.
