Someone much more tech savvy than me should try to use Charles Proxy on an iOS device and see how often your phone is communicating with Apple servers. It’s pretty wild.
It is wild but not entirely for the reasons someone might think.
I think everyone knows that a good part of the Apple app ecosystem relies on syncing data. I don't think anyone is surprised that a daemon is syncing your photos between your devices/cloud. Add podcasts, ePubs, etc. and you're going to have a busy network on your device. It's a reason in fact I use the cloud, sign in with my Apple ID. I can lose my machine but not my documents.
Maybe the thing that is more along the lines of what you're suggesting though is the network traffic that is seemingly less useful to the user (but useful to Apple). Various frameworks have appeared on the OS that allow apps to share analytics (pretty sure though these are the analytics that you are asked if you want to opt out of on an install/setup).
But because it has become so easy to do (in part because there is a framework to handle it, but also just the ubiquity of the presence of a network) lots of, I think, dumb data is collected to no doubt satisfy management/design as to whether some feature of an app is being used or is not being discovered.
The ubiquity as I say has made it too darn tempting for all parties (Apple and 3rd) to become lazy about how their apps are being used and to become too data hungry themselves.
I had someone recently ask me how I get feedback from my blog posts since there is no comment section, no analytics .... they wondered why I bother blogging at all.

You can also see this just by running an iOS simulator with Xcode on a Mac that has Little Snitch installed. The amount of phoning home by iOS (and macOS, for that matter) is shocking.
What is even more shocking is running an Android simulator in the same context. Literally dozens of Little Snitch prompts before the OS even boots to the lock screen. Not defending Apple here, but when I was developing a mobile app in both Xcode and Android Studio I noticed a marked difference in the amounts of phoning home.
Little Snitch could use a 1-click on/off ruleset for blocking all Apple network connections (17.x.x.x) except for the published whitelist of Apple notification servers. That would block most of the real-time phoning home. The block could be disabled manually for security updates. If notifications aren't needed, block all of 17.
I saw this idea implemented in the book "Extreme privacy: macOS devices". The author also provides importable profiles that you can switch between, e.g. to enable/disable security updates. I haven't tried them yet, but I am now more motivated to do so.
You can actually see the domains being contacted in the app privacy report. I’m not sure if it includes the OS level connections, but it includes for all apps, including Apple apps.
