I'm finishhing my basement and want to reduce noise from upstairs and vice versa. So I have access to the joists.
What would be best for the job at Home Depot? Fiberglass or Foam insulation or a special drywall?

I agree with Josh, 5/8 rock and unfaced fiberglass will do, this setup works O.K when it comes to soundproofing (mass).
However, for much much better results, I would also consider adding resilient channels. Resilient channels are steel channels that are attached perpendicular to ceiling joists 16" O.C and are designed to stop the sound transfer from the floor above...
Once the channels are installed drywall goes right over the channels...
Here up North we carry these in stores and they're priced out very reasonably ...about 6-7 $ for a 10ft stick.
Here's the product link;
