Virtual queues would have to be in place where standard queueing and physical distancing are difficult if near impossible. IASM could have a regular queue as the lanes are wide and the snake can be configured, Peter Pan would have to be virtual due to it's near claustrophobic queue width. Granted numbers of people may have to be monitored, but with reduced capacity maybe that doesn't become an issue.
Pirates - regular
Jungle Cruise - regular but they would have to really spread the queue.
Space Mountain - depending on demand they could go regular or virtual.
Test Track would almost have to be virtual just to control flow. I think it would all boil down to how effective an attraction would be at setting up the queue for social distancing. Same thing for whether an attraction would be on or off line. You could do Dumbo or Aladdin with only every other car occupied. Use every other car on the omni-movers and have CMs wipe down lap bars (at a minimum) after each ride. If anything I could see the water attractions like Pirates, Jungle Cruise, Splash NOT be in operation as they (Jungle less so but still) harbor moist humid environments, and that is not conducive to keeping particles down.
