My sympathies to you with the unplanned flood damage. You have a huge project on your hands there, and my word of advice would be not to rush into changes this big. We had a water leak-induced remodel that started over a year ago, and it's taken a long time to plan a new kitchen, but we're glad we took this year to research before diving into the upgrades. If you literally cannot wait that long to re-do, then perhaps consider hiring a kitchen designer in your area to do a lot of the difficult design and recommendation aspects for you. Under a normal timeline, there is so much you can learn by researching on your own, but in a time crunch, you'll be glad you paid for professional help to speed things up and avoid some pitfalls of cabinetry layout. One of the first things you might hear recommended for your space is to make the bar one-level, but if you want a total re-configuration, then the possibilities are limitless as to re-locating and adding features. Most new cabinetry designs are avoiding the multi-level wall cabinet heights and going with cabinets all the way to the ceiling for ceilings that are of average height.

You’ll need to post more photos (adjacent spaces) and a plan sketch with dimensions. Continuing the cabinets on the range wall all the way into the dining area seems to be the obvious option without seeing more.
