Generally speaking, prototype with the parts you expect to use in production unless there’s good reason not to. I think what you are describing can be better described as a “proof of concept” than a prototype.
Thats a good point, you’re right, thank you for that distinction! However, if I do prove that a concept works, and I find the SMT components I think would work in production, how do you prototype with such small components? I’m used to a breadboard and soldering, but with arduino sized through hole components. Is it really just a matter of being super careful and soldering onto the super small leads?
