Even with a right click after copying a file, there's no "Move" option. Your explanation makes sense but doesn't really seem supported with Finder's UX since the "Move" terminology doesn't exist anywhere
> How does one discover Cmd-Opt-V?
Keyboard shortcuts are not usually meant to be "discovered" (how do you discover ctrl+x?). You can learn and memorize them. Although, there is a common theme with the option/alt modifier on the mac.
Of course they are, don't be silly. Even in Finder, the "Édition" menu (I don't know how it's called in english) lists the keyboard shortcuts next to their names (copy, paste...). When you don't select anything, it even shows "Cut (Cmd+X)" grayed out! It just disappears when yous elect a file/folder

Seems pretty similar to apple, you have to know that pressing Alt shows additional information.
Navigating to the parent folder isn’t exclusive to a keyboard shortcut (⌘↑). It’s also accessible from the menu bar (Go → Enclosing Folder).
In regards to consistency, though I know this isn't exactly what you meant, I just booted a virtual machine with System 6 (released in 1988) and Command-Up was the same key command to open the parent folder. :)
You don't need cut for files, you either want to duplicate the file or move it. For moving you copy it (cmd-c) and then move with cmd-opt-v.
Cut doesn't really make sense for files. With text you cut out the text into a clipboard. Where does the file go when you cut it? Nowhere. There is no place where you can see that you had already cut a file but it's waiting for you to make a mistake and move it somewhere by accident.
Mac has a better duplicate/move UX paradigm and more appropriate for files & folders.
