You dont make clear so I will ask. Why are you focused solely on switch? Especially when grown in a dense monoculture, which is the fad theses days, it creates a biological desert that is pretty much the antithesis of productive well managed habitat. Certainly, if you are talking very thin strips, the loss is immaterial. However, if you are covering any meaningful amount of ground it can be short sighted.
If height is really a concern, and it usually should not be (deer are not that tall), both Big Bluestem and Indian Grass will usually get taller than switch especially if the switch is planted in a dense monoculture.
For maximum benefit to wildlife, with the ability to screen, a reasonably wide strip of a mix of Switch, Little Blue, Big Blue and Indian Grass planted at a low/medium density is probably a better choice.
