Given the o.p.'s dimensions the choice between mid-step or high step come down to functionality. Women that wear dresses or skirts find mid-step (or stagger, or mixte) designs easier to use than high step designs. Most will have ample inseam to straddle a 'mans frame' but culturally will be biased to the mid-step. I personally choose the 'large' frame of a S,M,L size offering. I compensate for the added 'reach' of the larger frame with a shorter stem. It is absolutely the o.p.'s choice which to try.
