macOS yes, though it breaks a lot of the “just works” style integration. On iOS I don’t know how you’d install anything beyond the apps included out of the box so it would be very limited.

iCloud and App Store are independent. You can sign in to the App Store but not iCloud. In fact I've never used iCloud on my iPhone.

Honest question: how? It seems to me that when I sign in to Apple ID, it automatically signs me in to iCloud. I've found this quite annoying.

Don't do that. You can sign in within the App Store app, but don't sign in anywhere else.

TIL thank you!
