VFD

Is it more cost effective to use a VFD instead of just getting a single phase motor? Be gentle, I know nothing here. LOL

I don't know about USA....but 3-phase motors are cheaper and more efficient than single phase equivalents.

Besides, a traditional single phase motor requires a 'start switch' or second winding to initiate rotation and get up to run speed.
