We use the OKTA IDP for Salesforce SSO.
What we discovered is that we can immediately onboard users to Salesforce from OKTA, which implies that a user is created in Salesforce from OKTA. This occurs when the user is assigned to an application in the OKTA. We are given a pop-up model to fill out in order to onboard the user to Salesforce.
What we need is assistance in restricting the Salesforce profile, permission sets, and public groups.
We do not want to display all salesforce profiles, permission sets, and public groups.
Set a default value to prevent user creations from OKTA.

Thanks for the additional details.
Unfortunately, that would not be something you can control from the Okta side. At best (although I doubt it), you might be able to configure that on the Salesforce side. Okta just does an API call to Salesforce for the information and displays the list based on the response received.
If you can find a way to restrict what Salesforce sends, Okta would display only that info.
That being said, this opens up the discussion of requirements: just hiding the info vs not using the info at all.
My advise would be to check in with Salesforce Support as well.
In the meantime, you can suggest a feature enhancement on the Okta Community page by going to the Community→ Ideas tab. Features suggested in our community are reviewed and can be voted and commented on by other members. High popularity will increase the likelihood of it being picked up by the Product Team and it being implemented.
