AuthN IS all the things that Dex and Hydra say they are not. I'll bet it could integrate with both given a bit of investment, e.g. by satisfying the "consent app" expectations.

AuthN does use as much of the OpenID Connect protocol as I could manage though. I started there and streamlined down to optimize for API-driven interactions rather than the redirect-driven interactions that are common with OAuth and OIC.
