Many of the older square taper BBs were asymmetrical. Newer tend to be like Shimanos with symmetry, putting the left crank much further out than it had to be to clear the chainstay.

One advantage of square taper if low Q is important is that you can get a Phil Wood BB with exactly the width and asymmetry you want. (It will cost real money and there might be a wait if it is not on the shelves.) Also for low Q, look for early-mid '80s Sugino or SR cranks. They were very straight.
