At my prior organization, we fell into category #4 - All unrestricted and budget relieving gifts--including gifts to support student access, academics, and athletics.
For instance, we often did crowdfunding campaigns, for specific department-related needs (such as funding a field trip related to one of the sciences). Those were all deemed to be put in the annual giving bucket.
