I really don't think your house needs much dressing up. It's a charmer in its simplicity. Perhaps, if you can get a matching or toning stone, surround the door with a slightly protruding stone frame? I wouldn't even repaint; the colour suits the house well.

Possibly paint window trim same as door...different lighting...

Your house is charming. I can see bright colour paint on shutters on either side of front window.

Paint garage door same colour as house so it does not stand out & take attention away from your house. In same colour, it will blend with house & make your house look larger.

There are fab porch lights @ places like Home Depot, which would add more character to front entrance.
