When you have a choice between two paths on a floor, and one of the option is a teleport room, it can be a good idea to save the teleport room for later. Teleporting between rooms doesn't consume food, so it's possible to wait until all teleport rooms are discovered before entering the first one. This will only cost you two steps to go in and out of the teleport rooms, instead of two per room, and can save a lot of food/steps. Less rooms entered/exited means a shorter path, and shorter paths are more cost effective.
You still want to consider room priority for survival reason -- if you know the mobs in a shop room is harder than the one on a food room and need to get some upgrade tokens, then you can make a longer path if it means you're more likely to survive, but to optimize economy you need to optimize short paths through floors, especially as your number of humans gets bigger.
