Since you can't get the appropriate sized shutters for the home (meant to be large enough so if they were to close they would cover the windows) I'd paint the trim white that surrounds the windows and surrounds the garage door. No shutters IMO.

Agree with Porter. You don't have enough space for the right sized shutters. Here is a brief article explaining why https://www.lifeofanarchitect.com/residential-architecture-101-shutters/

Besides, improperly sized shutters will ruin the nice clean lines of your beautiful home!

Your home looks to be a saltbox with side hall entry. No shutters on this classic style home. However, I would get those shrubs away from the windows where they're blocking light and view. Your money would be better spent on new landscaping that shows the beauty of your home.
