1Password already has support for this. Some would argue that you're defeating the purpose of 2FA if it's stored in the same way as your password, but it is pleasant.

Personally, I use KeePass and a self-managed password database. I look at it as the "something I have" factor being the database file itself, and the "something I know" being the master password that decrypts it. Then it doesn't bother me quite so much that the password and 2FA seed are right next to each other.

Does 1Password do SMS based 2FA code filling? I use it for sites where they let me use any compliant auth app, but I've not seen a way to get it to work for SMS codes.

No, only passkeys or TOTP stored in 1Password.

KeePass XC also does it.
