Not forgetting handling qualities and low speed/stall behaviour.
Wing twist/wash out
Flutter considerations
Location of engines or weapon pylons
Any low observable demands

In practice in low speed aircraft aerofoil section is not always significant. As speeds increase the choice of section becomes more important, and probably more open to compromise. Bear in mind a thicker section will be lighter, have greater internal volume for fuel, but slower. Everything is a compromise - the skill is where to pitch the compromise ... Many choices will work, but what will make money?
