The FIDO set of standards (UAF, U2F which predated passwords and passkeys) haven't even started as enterprise standards. There are multiple origins for what became FIDO, but the main ones I know are:

1. PayPal was looking for a physical authentication solution for their users, Michael Barrett was their CISO at that point and he became the president of FIDO.

2. Google developed Gnubby (which was internal, and therefore enterprise) and they wanted to push a similar authentication to their end-users, supported directly on Chrome. They wanted this to become a standards, so donated the underpinnings of the Gnubby technology which became FIDO U2F.

I might be wrong but at least these are the two parts I know.

And while the original FIDO could be called dual-use, Webauthn and especially Passkeys were developed to be first and foremost a customer-facing standard.

It doesn't mean they are not confusing, but they are clearly designed with end users in mind.
