How can I programmatically get a list of MacOS’s built-in keyboard shortcuts?

I’ve read about ways to manipulate com.apple.symbolichotkeys.plist to manage custom keyboard shortcuts, but if I understand correctly, this is just overwriting built-in shortcuts. If you delete the file, then MacOS’s keyboard shortcuts return to their built-ins.

What I would like to do is get a definitive list of MacOS’s built-in keyboard shortcuts and their corresponding action identifiers.

Is there somewhere I can pull this from?
