The problem with the suggestions here is that it puts all your eggs in the same basket. 1Password TOTP? If both your password and the TOTP are in your password manager, you arguably really just have a single factor, delegated to a third party (your password manager). PassKeys? Same problem. Storing your recovery keys in your password manager? You again just have 1 factor.
SMS is bad and should go away, but it isn't so clear what the replacement needs to be for most people.
