Your house is a fine one story Colonial Revival. A traditional Cape would have a steeper roof without dormers, no porch, no portico or any classical features like columns or pediments. A good choice would be a paint grade exterior wood panel door from TruStile in Colorado. They have more choices than any other company and it is easy to design a door with their design software.

I agree with marys1000: The sidelights should be the same color as the shutters (if you plan on having shutters). That will unify the design of the house and still allow the door to stand out. Our front door is Cottage Red, too--really nice color, I think. Our shutters are Essex Green (which is almost black). Lovely house, btw. :)

I vote for painting the sidelights on your home. The photos above are lovely but I think those work because of the amount of decorative molding that is around each door. You don't have much headroom above your door and I'd paint the sidelights to add more weight to your door area. If you want to get carried away with remodeling, look into redesigning the molding above your entry. ;) The example below is of DS's house before fixtures were replaced.

Painting the sidelights white will make the door stand out more, IMO. Agree with black or the current color and no shutters, wider steps, a larger lantern light (1/4 - 1/3 the door's height,) new landscaping, and a new walkway to the street. I think new landscaping will be highest impact for this house though.
