I grew up with this mindset on macOS/iOS, and went with it for many years.

Apple itself isn't consistent enough anymore for it to matter / there to be one true way. Pick a design system and roll with it, definitely - but slavishly trying to figure out the One True Way on a particular platform A) isn't likely to work out, even just focusing on design B) is a long-term handicap. Most people have a mix of devices in their life.

A soothing thought if that's hard to process: Jony Ive always had something to say about how the hardware becomes the app, especially post-iPhone. People expect the app to be familiar across platforms. (of course, there's all sorts of nerd-sniping caveats from there. Of _course_ you should use the platform's print dialog, etc. But don't get hung up on ex. what the Apple Reminders app looks like this year on iOS and OS X)
