| Webauthn with fido/u2f is supported on most websites and oidc providers.

I wish that was true. I’ve found that webauthn is becoming more common in the last year, but is still relatively rare. Many “important” sites and services make use of them. https://www.yubico.com/works-with-yubikey/catalog/ is a great place to see them, but they’re still quite rare as a whole.
