I agree with Ranton, assuming I understand that you've already decided on the cabinet choice? If you have and you've got the style and stain/paint picked out, I'd do the counters 2nd. I'd do the floors 3rd. Flooring, unless "it's in your face" attention grabbing, tends to just be the anchor and gets relegated to almost being overlooked. If you only want the blaring floor to take center stage,(that's your main objective) then highlight that and let everything else just be a supporting role for the floor. That being said, if you have a lot of movement in the graining of the wood (cabinet), you don't want to fight "movement with movement". So let's say you have a really intense movement in the wood grain that will show through the stain, I'd quiet it down on the granite and/or pick a quartz that is quieter to the degree that the cabinets are already "speaking". ** One thing, are you looking for a certain look or style? Can you tell us that if you know? The reason I ask is that depending on what look you want to achieve be it for example, sleek/modern/minimalist, Tuscan/Mediterranean, French country, Craftsman/earthy colors etc., you get the idea. So write down some basic words that you think of when people say (your) XYZ style. From that, when you are looking at each material or pattern, what is the first word that comes to mind when you see that pattern/color/style in the granite yard or flooring? If what comes to mind belongs to another style/look, you may be about to combine things that don't belong in the same "box". Something to think about...... Oh, definitely choose the granite then choose the backsplash color/pattern/material after that. Regarding flooring, ask your DH the one thing that he wants to first be noticed in your kitchen. I.E. if someone where to come for a visit after it's completed and says they love XYZ about it. What element would be choose as the strongest thing that stands out when you walk into your kitchen? I know on some of these design shows when it comes to pattern be it fabric, upholstery, wallpaper, whatever, they suggest that the "scale" of each element not be the same. Like if you had a large print on a fabric in whatever color you'd want to choose a smaller scale on the other elements in the room so they don't compete. If you've got several large (busy) 'in your face' patterns in the room, they compete with each other. The result is that the eye bounces around constantly from large pattern (i.e. movement) to the next large/busy/heavy movement pattern. What happens is a feeling of vibration and competition between all the elements that is not restful to the eye or mind. I know I'm jumping around here. All these things are coming to mind that might help you so I'm just throwing it out there before I think of something else. Question: Are your and DH's style the same or different? If they are different, there was an HGTV show that integrated the two (sorry, can't think of it or the host's name) but there were some good points in how the host did it. Good luck and let us know how it goes. I don't know if I've helped here or not, but hopefully it will spark some thought processes that might help you.

My architect/designer sez these days Granite prices lower than nearly all the other solid surfaces and contributes to its popularity espec if u r not looking for esoteric colors. Marble, which i have alot of in our offices for multiple conf and other tables, even in a dark shade, is "delicate" in the sense that it is brittle and can crack etc, and in a lite color maintenance is brutal b/c it will stain (not an issue with, say, a dark wine color marble like we have but it does crack). I have seen some Granite Tiles used where costs need trimming and when done in larger tiles, and done well and creatively, the look is acceptable and grout lines minimal. So you may be able to compromise in one area this way...it is the long lengths of granite that set you back. Soapstone is a joy b/c of the touch, and if you like it oiled up black, stains not an issue. Natural colors of soapstone are lovely but we have only used that in dining area cabinet tops in bar-like areas...and natural is not good for kitchen. (It also is great in bathrooms, even flooring b/c it isnt slippery). But soapstone is a more old-fashioned/colonial like look...not slick and modern My favorite for counters is Stainless Steel!!! installed in 1993 i still love it. But i would then warm up the look by having the island be done in something else. Also St.Steel with dark wood cabs really look warm and approachable.

Egan-I would reduce island length by around 12”. I would eliminate pony walls on ends and use decorative cabinet end panels and reduce 18” cabinet on far end to 12” cabinet. Make sure your cabinets are designed with proper metal support plates for slab. 12-13” overlay for stools is tight. I would expand to 16”. Most slabs can accommodate that total width. 36” deep plus 4” more would mean slab has to be 40-44” wide and 108-112” long. That is doable for most slabs without seams.

Here's a site that has a lot of options and gives you things to consider. https://www.barstooldesigns.com/ I've been pondering my counter stools for two years while I make do with $3 Habitat Reuse place holders. If wishbone chairs came in a swivel option, I'd be all over that! I have decided I have to have swivel, my place holders are and they are great because they don't require a lot of room for people to get into or out of them and they don't scratch the floor because they have very little movement due to the swivel. It's those kinds of things you want to have figured out before you decide and IMO, you have to live in the space to do that. Your mood board looks nice.
