I'd put the cooktop on the short wall and move a counter-depth fridge down far enough to make space for a reach-in pantry and a dish hutch. In this plan the prep and cooking zones are on one end, with clean-up and dish storage near the dining area. A helper can unload the DW and gather dishes to set the table, without interfering in the prep and cooking tasks. Incoming groceries can be placed on the table or island for easy loading to the pantry and fridge. The pantry and dish hutch could be switched--if you don't mind taking an extra step or two to unload the DW--but I like the landing space on both sides of the fridge.

I gave two locations for the MW--a drawer on the island, or a shelf beside the fridge, depending on the better location for your husband's comfort. The pull-out beside the ovens could be used as a broom closet, for extra pantry storage, or for small appliances.

The island is drawn as 42x96, which would account for 24" deep cabinets, a back panel, 15" seating overhang, and a front overhang of 1"-2". DW return panel and side overhangs will add another 3"-4" to the length.

If a 36" CD fridge doesn't provide enough storage space, you might consider a wider model, separate columns, or consider recessing a standard-depth fridge into the wall behind it, to gain a few inches in the work aisle.
