Sorry - late to the game. I'm an architect and did my own house 20 years ago. Here are some of the things that i would either do or do differently:
Double oven, switched exterior outlets for Christmas lights, switched exhaust fan for the garage, install plumbing rough-in for a water softener, construct exterior walls with 2 x 6 studs to accommodate R-19 insulation and install R-30 insulation in the roof, spend extra for high efficiency heating / cooling system, think about design for future years, including wider doors and hallways plus add wood blocking in bathroom walls by toilet for grab bars, don't jump over dollars to save dimes (i.e. if you can afford it now and want it - do it! It only gets more expensive later).
