It doesn't matter if they can wear metal armor. They will not wear metal armor.
Fighter: "Here, wear this half-plate because you're proficient."
Druid: "No. I will not put that on. It is unnatural for man to be clad in metal."

Eh, it depends how closely your table follows the fluff attached to the classes. There's that whole spectrum from strict adherence to total disregard and the OP's table might fall anywhere in the mix. Suggesting half plate because there's no mechanical penalty is a reasonable enough thing to do.
