How to recover iCloud data on a new iPhone without the other device's password?

In order to continue syncing the data on your new device, you have to delete that End to End encrypted data that is currently in iCloud that is unreadable without providing the requested information. You should see that option to delete the data after choosing to resume syncing and if you don't enter the incorrect password to the requested device a couple of time.

Photos are not End to End encrypted unless you are using Advanced Data Protection, so those should have been synced if you were using iCloud Photos or from the iCloud backup for that device. Messages are End to End encrypted and the key to remove the decryption is the Passcode from the device that synced it. You don't need to have access to the device, you just need to know what that Passcode was.
