The Android experience is quite a bit more wanky than Apple's walled garden. I moved to Android a year ago and it took me months of fiddling until I was satisfied. Google really tries to give you their own not-that-walled garden, giving you an Apple-esque experience. If you are not 100 % invested, it could get finicky, though. The vendors usually provide their own standard apps, but more often than not, I find them unpolished.
Regarding Log in with Apple, you could, from what I experienced, get problems, as some Android apps won't let you sign in wit Apple, and even websites don'support it all the time. Take Tripadvisor as an example. Create an account on the iOS app, and when changing to Android, you're basically locked out, because neither their Android app nor their website support Log in with Apple.
