I thought phones had hooks for notifications n stuff regardless of if the app was open. Shouldn’t that cover most things you care about in the background? Am I wrong or is this different for Android (I’ve only used apple)?

AFAIK, FCM is essentially a service running on your phone that receives messages from Google's servers and forwards them to your apps. And backend servers can send messages to those Google servers.
