On the contrary, any reasonable Android device lets you disable far more tracking than iOS. On iOS, you cannot get your location without telling Apple or install an app without telling Apple. You cannot even use your phone without an Apple account. No such problem on Android.
2) You're right. It looks like it's possible to set up an iOS device without an Apple ID, but you obviously won't be able to install any apps. I couldn't find a list of what does work if you don't enter an Apple ID during setup.

I have used Android for a decade now. I recently got a Poco X3 pro. Having had a chance to use MIUI, I immediately unlocked the bootloader and installed Lineage. Nobody uses open camera. I joined a telegram community and installed Google Camera which allowed me access to things like night mode and wide angle lens. If I wanted to use purely AOSP, I'd lose access to the wide angle lens on my phone as far as I can tell.
