If one is obviously a main road then it's a two way. If neither is, then it's a four way. If the intersection is lightly trafficked then there's not any reason not to make it a four way because it won't cause meaningful delays anyway. When a county has several hundred country road intersections that get a few dozen cars or less a day through them, it doesn't make sense to even spend time studying each one. Just throw up some stop signs and consider the matter resolved.

Or do what they do in the UK. For all of these, make them 'mini-roundabouts' which is literally a dot painted on the center of the road. You follow the rules of the roundabout without building one. Works just as efficiently as a four way stop with light traffic - actually more, since you don't need to stop if the intersection is empty.

And then every single car must stop. That's a huge waste of energy.

The European way requires half as many signposts, and at most half as much stopping and starting of cars.
