Earlier quoted context omitted.
"macOS Finder": you are talking about that software that rename folders when you press the enter key? :p
Can you give a reason why Enter to open a file is ideal, other than just because it's how Windows does it? The Windows Explorer uses Alt+Enter to show the properties of something, and in games and other apps that shortcut means Full Screen. Also, why does Alt+F4 quit an app? What does F4 stand for? Compared to Cmd+Q to Quit or Cmd+W to close it's a lot less intuitive. And so on and so forth.
As for Cmd+Q and Cmd+W, those might be somewhat more intuitive, but only for some languages, and arguably only very vaguely intuitive for Cmd+W even for english speaking people.
But then again, I don't think there is a real notable difference in the end between most modern systems. It's more of a question of what we are used to.
