While Fusion 360 does have many non-NURBS procedural surfaces, they definitely also have NURBS. Otherwise you wouldn't be able to import an IGES or step file.

Using a solids kernel with procedural surfaces can help many cases, as you keep the modeling tree around and can recompute portions at higher tolerance as needed. However that's just another cumbersome workaround to the fundamental problem that the math doesn't have clean solutions.
