yes, all iCloud data that are checked in Settings> your Account> icloud> saved to icloud loaded fine. for me it included photos, icloud drive, icloud mail only, password keychains, notes, messages, health, contacts, reminders, wallet, game center, shortcuts and other apps. I checked everything in there and synced them up with icloud.
Following are the tasks I had to do manually:
1) Mail - create all mailboxes (I had the passwords saved in vaults like passwords, authenticator app, chrome)
2) Install all the apps this is painful but again saving my passwords in the the vaults helped be login faster - I am on apple upgrade program and iCloud+ user so really never deleted any app since iphone 13, this exercise made me not install many apps that I never used since years. But i still had to spend time remembering and installing all the needed apps.
3) I had several wallpapers and all of them are gone.
4) If you are using authenticator app for work or personal use, you may lose them, I had to setup everything again. It was painful for me since.
