"... Should we push the exterior wall back even further so there's still room for an island & walkway?..." If budget allows - that's what I would do. Here's what you could do if you can push the external wall out to be flush with the FR wall on the right (not counting the bay). I think it opens up the Kitchen more and gives it a more spacious feel. Note that I flanked a 48" window with cabinets. If you would like a bigger window, consider eliminating the 15" on the left (or merging 12" of it into the easy reach in the corner) and shortening the 51" to 48" or 45". You might even consider a bumpout in front of the window - say 6" to 9" - to give you more room behind the sink. It depends on what's outside the window - you don't want to put a bumpout where someone might run into it. I put in 3" deeper counters along the range wall. You now have a real pantry - much less expensive than one pantry cabinet, let alone two! It's also much better/efficient storage. The pantry is 81" wide with 12" deep shelves on three walls and two 24" swing out doors to give you 48" of doorway space when needed (e.g., when putting away groceries.) I enlarged the doorway to the Powder & Laundry Rooms to 36". When carrying baskets to/from the Laundry Room, I think you will appreciate 36" instead of the 31" there right now. The Family Room entrance is almost 12' wide. But, to support the span, I added walls on each end of the opening. The table will fit in the space. I put in a 42" wide table, that's DR sized, so if you have a narrower table (39") for the space, there will be more space than I show. The aisle b/w the table and the island is 60" - that's the minimum I'd do with seating on each side of the aisle. The refrigerator is on the range wall so it's easily accessed from the Kitchen w/o having to cross a potentially busy aisle to/from the Garage. It's also on the periphery so it's someone from the DR, table space, or FR an get to it without crossing into the primary work area of the Kitchen. The refrigerator is a standard depth (36") and is recessed into the wall behind it a couple of inches. With the 3" deeper counters and recessing a couple of inches, that's 5". The refrigerator now looks counter-depth, but it's a less expensive and larger size. The island is much bigger to encompass the post. To add symmetry, I added a post on the other other end as well. With the additional size, you now have extra storage for seldom used items in 12" deep cabinets under the seating overhang. The island provides 53" of prep space. The trash pullout is located in the primary Prep Zone (island) but is close to the secondary Prep Zone, the Cooking Zone, and the Cleanup Zone. (You generate far more trash & recyclables while prepping & cooking than you do when cleaning up - and for a longer period of time. So, it makes sense to put it in the Prep Zone.) OK...here it is! .

I think slender buffet lamps on each end would look great! I say no pendant lighting..that way it will look unique and not like a residential kitchen. I love these metal finish lampswith matching metal shade from Restoration Hardware..offered in 4 finishes...

Different goals come into play. Task lighting for when you work at the island counter requires 450+ lumens at the surface. The source should be placed so you don't shadow the work with your body. Ambient lighting is another objective. Recessed led cans on dimmers can do both. Pendants on dimmers or pendants and recessed lights can also do both. In addition, pendants can be decorative. Adequate task lighting is often missing in kitchen design.

I think if you pick a smaller light fixture it will look better with three. These are very large. And seem more like bedroom lights… 💗 What about one of these? https://www.crateandbarrel.com/maddox-white-dome-pendant-large-with-brass-socket/s313135 https://www.overstock.com/Lighting-Ceiling-Fans/Chandeliers/29878/cat.html https://www.homedepot.com/pep/KICHLER-Merriam-8-in-1-Light-Classic-Gold-Farmhouse-Kitchen-Pendant-Hanging-Light-82367/314569558?source=shoppingads&locale=en-US&&mtc=SHOPPING-RM-RMP-GGL-D27-Multi-MB-KICHLER-NA-SMART-NA-NA-MK597961800-NA-BT3-4044-NA-NA-NA&cm_mmc=SHOPPING-RM-RMP-GGL-D27-Multi-MB-KICHLER-NA-SMART-NA-NA-MK597961800-NA-BT3-4044-NA-NA-NA-71700000101159075-58700008089988825-92700073545079508&gbraid=0AAAAADq61Uf3exlDsCL_Gj_1an2UML4UN&gbraid=0AAAAADq61Uf3exlDsCL_Gj_1an2UML4UN&gclid=CjwKCAjwzY2bBhB6EiwAPpUpZtGnzHOa2nijUEYTFLlADebKRLOreRKWU3FwOHRIL34oRTp4qhASexoC6KIQAvD_BwE&gclsrc=aw.ds
