Contrast is the key. I really like the dark grey front door mock-up. I would explore matching the garage door with that color.

Like the pergola over the garage door idea. If built to be sturdy enough to walk on it, then it could serve as a fire escape route should the need ever arise -- certainly hope it never does. You might also consider painting your step rails and side supports the same color as your siding unless you're planning to have a wood finish door and/or a rustic porch and post addition over the entry at a later date, in which case you'd want those additions to have the same wood finish. (Might apply to any pergola over the garage as well.) https://www.bing.com/images/search?q=images+rustic+porch+and+post+entry&qpvt=images+rustic+porch+and+post+entry&FORM=IGRE

Those shutter are not appropriate on those windows so forget making the garge door work with them. The doors you show are MCM style and not at all craftsman which BTW will never be your house without huge $$$$$ spent. I would remove some of the growth covering your entry for sure , IMO it is important to see the entry to a home. I think darker trim and darker windows could be a huge improvement over the white and honestly a new paint color would be a great idea. Then do a nice wood door with windows but not quite as modern looking as the ones you show.If you are painting the siding then I would plan on removing the arched window it really does nothing for the house.

Here is my vision. I like this tone of blue. Start by painting storm door black. That repeats the black hand rail and I added a decorative light in peak. The blue goes well with roof. Then paint front door blue as well as trim around door. Then, as you are able paint posts and other trim in the blue. Brings a beautiful look to your front appeal.
