This seems pretty basic, but I believe that the reason some male traits and some female traits are ideal (despite being contradictory) are so as a primitive being, you wouldn't put your dick in the wrong gender. Like a large jaw and brow ridge is seen as good on men (it symbolizes high T) which is good for determining that the person is indeed a good MALE specimen to fuck. But for women, a small jaw is preferable because it symbolizes high E and low T, which is a good hormonal balance for a female. So essentially, if this system weren't in place, in nature you might have tried to fuck a dude because there were no judgemental factor in determining the gender of the other person. Basically this "gender judging" phenomenon is in place so that you have sex with the best of the opposite gender, and don't have sex with the same gender.
