I don't think any state makes it policy to only offer one or another.
Here in Indiana we used to have two placards. Last time we went to renew they told us they were moving to plates as the default but since we had two vehicles we could plate one and placard the other. Probably should have plated the truck, since he drives that one most often, but for some reason we plated the car instead, which is mostly driven by me. So our plated car is almost never parked in a handicapped spot, because unless he's with me I'm not allowed to do that (and wouldn't anyhow, since I don't need the spot for me).
I think if there's just one vehicle they want it plated. I think it's to cut down on passing placards around but I'm not sure. I don't this it's mandated
, just strongly encouraged.
