> I currently use Google Voice for almost all SMS 2FA

Same.

I have financial accounts in multiple countries, many using Google Voice for 2FA.

However, whenever I create an account that allows anything other than SMS for 2FA, I immediately switch to that instead. I use an offline TOTP authenticator app, and backup the token secrets in something that's not linked to my Google account.

This greatly limits my blast radius, I think, because I can access my most critical online services without access to my Google account.

My Google Voice number is the only phone number I've used for 15+ years. It'd be a real nightmare if I lost access to my Gmail and/or Voice.
