SA/SO NKO/NE, panic shot + overflowing the sink to lure both guards out of the room with the egg and the classic pool of water + loose wire combo
Pretty boring (besides the “figuring out how to move the guards in the safe room” part) but I went for something even a new player can easily do.
Pretty sure you might not even need to do panic shots and can just use all of the distraction prompts in the bathroom to distract both of them and have enough time to slip in and out.
