Having the garage doors blend with the house downplays their prominence, drawing the eye to the primary door.

I don't love blue as a house color, I would actually go darker for everything like urbane bronze or Black Fox. Please paint over the electrical fittings no matter what you decide.

All the images of homes painted Polo Blue have a lot of white trim which "breaks up" the blue. Agree with Hallett, go darker, even if it's a darker shade of brown. IMO modern landscaping will give you more bang for your buck.

Can I talk you into swapping out the Adirondack chairs for a modern bench?

I would paint EVERYTHING a dark color like Black Fox. No white trim at all. Why pick out the soffit and windows with white? I would choose a fabulous color like a lime green for your front door. But try painting your trim the same color as the body of your home. It is a lovely home, by the way!

Yay that would’ve been my suggestion too.
I’d add some cedar elements too.
And I would probably do the mud room door the black and maybe cedar for the garage
