New members moderation + directing them to certain spaces

I'd like to know if there's a way to moderate new members before they can access the community, after registration?

Second thing I'd like to do is a form at registration step where they will select some category of business they have, and depending on their choice they will be granted access to certain spaces automatically, if that's possible let me know how, thanks! (I have FluentForms and FluentCRM, maybe there's a solution with it?)

Then another thing I would consider be doing is lock certain spaces and automatically unlock them if they have been completed, or maybe this has to be with courses. The idea here is that I want to force users to finish the "Get started" space before they are able to be granted access to other spaces.
