This was the issue in the license plate case that came up a year or two ago before SCOTUS. The Court found that license plates were the government's speech, not the driver's, and the state could limit, our allow, pretty much whatever it deemed appropriate.
Technically, yes, but they already allow the Confederate Flag in these cemeteries: https://en.wikipedia.org/wiki/Southern_Cross_of_Honor
I'm sure this will be challenged in court and, while you're right about government speech, it is going to be challenged on what people are allowed to place on the graves themselves.
