IMO get an actual KD not some cabinet salesperson I never like a range and sink directly across from eachother and fridge to sink should not pass the range.

2 pantry columns on back wall...a separate pantry room and servery ? in the ante space. skip the shallow pantry on the side wall. extend the island and stagger sink w range so not back to back. you want to pivot w items out of fridge so more island behind fridge is helpful......you will make up for the shallow wall elimination w drawers in island .. I doubt you have the storage maximized in the pantry walk in . Answer is plan B but get going w important tweaks.
