>>60955562The one with the shutter to the right of the entrance generally isn't worth doing since you're only gonna go there the one time after you initially do and it's when you first get the planks.
There are 2 windows there but if you absolutely need to do one I'd recommend the one not inside the room with the chairs blocking a door.
By the interrogation rooms do you mean the one where the guy gets cut in half by a shutter at the start? With Claire I don't think that's overly worth doing but put those as your 2nd priority over that first hallway I guess.
