Here is the picture of the house

Gray and white is common, on such a small house, I would not contrast the gutters.

No to painting the concrete, power wash and remove all existing flaking paint back to original and seal the concrete. Get an area rug to fill the porch floor. No shutters, save your $ for landscaping. ne light fixture, and house numbers.

Downspouts and gutters are not IMHO design elements so best when match the roof for th gutters and the siding for the downspouts I for sure do not like the white on those pillars . Maybe clear cedar for those posts and the front door and then adrk gray slate or tile for the porch floor and the steps.

You mentioned tile for the floor. I would definitely do that, rather than paint it. Even powerwashing and removing all the paint, and putting a sealer on it, is better than painting. Unlike above, I like my gutters and my downspouts all the same color, rather than matching roof, or siding. Yours look like they have been previously painted, but, if they were new and had the baked on finish that comes on them, I wouldnt paint them ever, unless, they looked bad.

Gutters aren't a design feature. You want them to match the color of the trim or the siding, whatever blends in best. Shutters might work on your house --- you want to mock up the size of shutters on the window under the porch. You'd need to remove the trim around the windows, though. I happen to think the windows look nice as is, but you do have a house where shutters might work. You want to decide before the siding is installed.

I'd paint the cement foundation on the right a darker shade of the same gray as the siding, although, leaving it might work, too, on a gray house.

I think a light gray would be pretty on the house. Then a wide white trim around your windows to tie in with the porch columns. I agree with power washing your concrete and then sealing. I live in southwest Florida and it's very common here to paint pool decks and even driveways but it's always done with an opaque concrete stain that survives the harsh sun so that could also be an option for you. If your front door is currently painted and not wood, I would suggest a brighter color to make it more welcoming. It also looks as though your pavers leading from your driveway could use some re-working. They look a little uneven. Perhaps 2x2 pavers would work a bit better. Vertical house numbers on one of your columns would make it easier for guests and emergency personnel to find your house.

Gray is such a depressing color for a cute cottage. Pick a cottage appropriate color. A pale yellow, or blue, or even a pink or lavender!

A fabulous encaustic look porcelain for the porch could add to the charm. https://www.crossvillestudios.com/Products/DUR-CASTELLON

@lisedv THANK YOU so much! That is awesome and so helpful. I like that color! They should start putting the siding up tomorrow.
