maybe a nice big white farm door ???

A Dutch door?

But, yes, half-glass with muntins would be a compatible choice.

Appropriately-sized shutters would do wonders too.

To improve the front, remove the stick-on shutters. Notice how the shutters on the Three-bay Colonial house posted above would cover the windows if closed and the shadow are the bottom. That shows they are real and look right to the eye. There's something off about the windows too. The lower ones don't look like they open and the uppers one-over-one doesn't work. What year was the house built? Also just noticed how high the front door stoop is, needs some kind of railing for safety.

If that's a steel door, dents can be repaired with autobody filler and careful weatherstripping to stop drafts.
