Foam board on concrete walls question

My first posting! Thanks in advance to such a knowledgeable group.

I'm planning on covering the basement concrete walls with 2" rigid foam board (for insulation and vapor properties). I'm also planning on installing Tyroc or DRIcore insulated subfloor panels, before framing any interior walls on top of the panels.

My question is... should I install the foam board on the walls first tightly from ceiling joist to concrete slab and THEN install the subfloor panels? Or vice versa? My gut tells me the to put the subfloor down second because I think there needs to be a 1/4" gap for ventilation, which would make the gap between the subfloor and the wall board.

Can anyone please confirm if I'm thinking about this the right way? And in general do you have any thoughts to share on where insulated walls meet insulated floors?

I would run the panels to the floor and butt the subfloor up to it, otherwise you are going to have a cold spot at the bottom of you wall that could casue condensation problems down the road.
