Select you material based on chemical compatibility, and then select the lowest stress to seal material that is compatible. Full face gaskets have ~4X the contact area of ring gaskets, so you'll need a low stress to seal material and high strength bolting (B7 or Grade 8).
A gasket manufacturer, Inertech Inc., makes a low stress to seal expanded PTFE gasket in a reduced area design which is ideal for flat face flanges. This would be your best bet for most chemical services at temperatures <400F.
