This seems like a unique kind of home to design! The only one I like at all is B - I would absolutely avoid a kitchen with a trafficway through the main work circuit. It's probably one of the things that works about the current overly cramped 3-lane kitchen.
I would open up the pantry, yes, and move the fridge to the exterior wall just inside that space (so it would be to the right of the sink) then put some 12-15" deep reach-in pantry cabinets on the former fridge wall. Keep the wall between the back stairs and the hall 2/bedrooms area clear for flow.
Not a fan of angled segments as they immediately make the kitchen feel like it was installed 30 years ago.
You need at least one 3-stack drawer cabinet for pots and pans, and a couple 4 or 5 stacks for all the shallow things that work best in thin layers like wraps and foils, spices, cooking implements, potholders and spare towels and rags, etc. You'll be able to buy fewer cabinets overall because of the great efficiency of drawer storage.
That 3'2" walkway from the back spiral stair is unnecessarily tight. 3'8" would be much more comfortable and you appear to have the room to borrow from in the U (I would keep it at least 4"6" counter to counter at that end).
I bet some of the very talented folks here will come in and erase the space, giving you their own from-scratch ideas. I'm looking forward to it!
