I have the opposite opinion for macOS shortcuts vs Linux/Windows/IBM shortcuts.

Practically everything is handled with Cmd, with Option/Shift/Control being modifiers. It's the exception if something is handled exclusively with Option/Shift/Control, example being web browsers and Finder for tabs. Text selection is superior in macOS, and anyone who argues PgUp/PgDn/Home/End being a better solution in combination with Shift and Ctrl is insane. Depending on the port of a 3rd-party application, it may adopt macOS shortcuts and be consistent with everything else, or keep IBM/Windows-style shortcuts and break compatibility with other apps.
