insulation over concrete slab

Hi all:
In the process of a gut rehab of my kitchen. A portion on the kitchen is built over a concrete slab and has 2 inch joists sitting right on the concrete. I just installed a vapor barrier on the concrete (builder's felt under 6 mil). My question is what should I use for insulation. Thanks

If it matters, I will use 3/4 ply, 2 layers of underlayment, electric radiant heat and then ceramic.

Rigid board insulation and you have to install a radiant barrier over the insulation if you intend to use electric radiant floor system.
