More and more homes use wood upstairs. It is a good choice in bed rooms when allergies are involved. Area rugs will keep the noise down. I guess you need to think about how you will be using the rooms. Insulation in the ceiling will assist with the noise transition as well.

If you are noise sensitive and will be bothered by footsteps when you are trying to relax, you should find someone local who like me, can meet with your architect or builder to integrate noise control strategies. Noise is very expensive to fix if new construction has to be opened up again.
