Authentik is a very capable open source Identity Provider (idP software like Authelia, Okta, Keycloak etc.) which probably has the most features of any open source identify provider available. It's also still under heavy development with stable releases being made every few weeks.

Nextcloud supports pretty urls which is a fancy way of saying it will not display the 'index.php' part in the address bar.

But we can capture the alerts from the system and get them out in a roundabout way.
