SubD modeling has in my experience always called by a separate term from sculpting - box modeling.
I also wouldn’t recommend any professional to be both a box and NURBS modeler since they are such different approaches.
Another class of modeling is A-class surfacing which requires a specialized workflow only highly trained professionals master. Often employers ask for surface modelers while they actually want A-class surfacers - this is something to keep in mind in a world where more and more self-trained people are stepping into 3D modeling.
