Many thanks to all of you. I and my husband had chosen a color each, finally we both agreed on the concept of ASV that let the backsplash tell all the story. ..will post the pics once it's done. Greed for orange one is pestering me ...will find a place for it somewhere else. :-)

Unfortunately all your options require custom work: It looks like you need an 18" corner cabinet. You will have to modify the last wall cabinet on the left. As I am eyeballing it, you should be able to cut the last cabinet in the middle and then shorten the left section to fit the space of the wall next to the door trim. It's an option that makes the area looks symmetric. Or you can install shelves over the sink. I would not recommend it because it will take the looks away. And the last option will be to remove the last cabinet, shorten it so it fits over the sink and install a single cabinet where the double one was. This will leave a triangle space behind the corner where the two cabinets will meet. You can block the space under it. Hope this helps!

Option 4. I would not have more than 2 different cabinet finishes. Darker, grounded look for the base and island, with lighter, airier look for the uppers would balance the room.

First one is okay with!! I think you have to match your backsplash n countertop similtaneously, Flooring could have been different pattern/option than what you have to!! First complete bottom front way, then it can be looked at further....
