Administering Permissions in Keap Max Classic

I’m new to Keap Max Classic and as an Administrator I’m used to things like Active Directory OU’s and assigning permissions via IAM. When I look in Keap I see 11 tabs with dozens of permissions below them.

I really have five classifications of Users that are going to have slightly different permissions on them. Is there a best practice or template I can use when it comes to globally classifying a User and what they need to to do in Keap?

There used to be User Groups that you could assign, but they (except for Admin) are deprecated.
Now, you can just copy the permissions from one user to another, so if you have one user from each of your groups, when you add someone new you can just copy the permissions from that user.
