I switched away from Google Authenticator app to Microsoft Authenticator app for that reason (it is a generic 2FA, so you can use it as a 2FA for google logins and any other services just fine). One important difference is that Microsoft Authenticator supports recovery from iCloud (in cause you are on iOS; there is probably something similar for Android too), which is something that Google Authenticator does not. So in case my phone explodes, the only thing i need to recover all my 2FA stuff is a recovery key for iCloud (which i can print out and put in a few places, like a bank storage cell and my parents’ house), because my Apple stuff is behind 2FA as well. So essentially, i just pick up my recovery code, buy a new iphone, authenticate using the recovery code, it restores all my data from iCloud backup, and my Microsoft Authenticator app has all my 2FAs for all services i use it for there. It is a fairly recent feature for Microsoft Authenticator on iOS iirc, they added it less than a year ago. A few other 2FA apps, like Authy, support that type of 2FA recovery too (and Authy specifically had that feature for much longer).
