Power to you. We had a disaster (frozen pipe) in January and lived without a kitchen for almost 5 months. Just finished out project a week or so ago. I never realized how often the kitchen sink is used, until I had to live without it. The temp sink is an AWESOME idea. Wish someone had given me that idea when we were making the rounds to the laundry room sink every 10 minutes. If there is any silver lining, once its all done, its such a relief. I still can't believe we have a fully functional kitchen when I go into it every day. Adding a link to our final product. Here is a link that might be useful: Finished kitchen pictures

More info would be needed to give actionable advice. But @palimpsest has made good assumptions and his solution is excellent to meet those. Seeing that layout, calls attention that you may need layered lighting. A jewel of a hanging fixture to wow guests and them circulating through the entry. But then some workhorse lighting for everyday living because you may have some dark areas that the jewel fixture does not address and you don't want to leave it on all the time - like the tight hall next to the bath, the recessed vestibule in what appears leads to an office, some sort of inset area behind the ref's. And, it looks like a contemporary design with an entrance canopy, so there will assumedly be recessed lighting under there. If you have large glass doors or transoms then that design language of canopy lighting should carry through to the interior (or vice versa).

I agree that a much larger rug would have greatest impact. Also, the picture is too high. The bench seems misplaced in front of the door even if you don’t open that side. Try swapping it with the plant stand & palm - just not having a seat there ’feels’ better. The palm will be better with the small items you have on wall. Try a different seat in corner by stairs - use one of your dining chairs for a mock up since it can be placed at an angle. If that looks better & you want a seat in entry then maybe try a small upholstered chair in the spot. If you want a more glam look, the wall hooks at left of door can be a more ornate piece than what’s there looks like.

No gray. You need tiles in this palette, ivory and gold/brown, to echo the floors and stairs: Here's a tile from Datile in a smaller pattern. You might be able to find a wood-pattern ceramic tile that matches your hardwood. With a coordinating mat over it, this solution could work. Flor.com has carpet tiles you can mix and match to create a floor mat; Choose Flor tiles that are indoor-outdoor. Or get a piece of industrial carpeting cut in a tweed of ivory and gold/brown to use as your floor mat. Since you have a white door and white molding, then keep stair riser painted white. Since you're spiffing things up, maybe a more attractive shoe shelf would help. I don't know if this would fit. It's from Wayfair. Shelves are 10" deep, which is probably not as deep as what you have.
