100%, living this for many years. Google IDP is great for a shop who doesnt need elaborate identity needs. It quickly falls apart when trying to manage an enterprise of any complexity.
Okta is quite flexible and supports a lot of tech you want (WebAuthN/SCIMv2 provisioners for popular platforms/all the SSO/API integration/workflows), but comes with it's own set of warts and dysfunction (api rate limits, quirky AD integration with anything complicated).
Probably any of them would be suitable, if you are comfortable building your own custom tooling AROUND their APIs. Almost none of them will do exactly what you need out of the box.
