I find the layout hard to read. Can you post a larger/clearer photo?

Is this any better?

These are just a couple of tweaks I'd recommend.

I switched the fridge and beverage center locations. I don't see how your congestion issue when the fridge door is open problem is resolved if you keep the fridge as placed in your plan. Your location for it also means the island is a barrier island to the prep and cook areas. It also makes sense to me to have the beverage center nearer the dining room when entertaining. The red lines indicate the path you would have to take if the fridge stayed there. The green line is the shorter path with the new fridge location. Multiply that path numerous times in the course of preparing your meals, especially when you entertain dozens, and those extra steps really add up.

I suggest you have the upper bleed into the corner instead of making the turn. This allows you to put bigger windows on each side of the range for more light and better views of the backyard to watch the kids.

funkycamper, thank you so much for the feedback! I did actually consider putting the refrigerator where the beverage center will be, and there were a couple of reasons I decided against it...

The first is that the space is only 69" long, so there isn't enough space for the 48" built in refrigerator plus the pantries, so I'd still have to have some of the pantry space be over where we have it shown. One of the reasons we are getting rid of the pantry that is there now is that it's pretty annoying having the pantry space split across the kitchen like that, I frequently find myself running back and forth from one to the other. Plus, if there is something I need from the other pantry I would have to go over to that side anyway, so it would seem to be more convenient to have the pantries and fridge together so I only have to go to one area to get the food.

The second reason is that currently we have a regular depth refrigerator in that space and the opening to the dining room is 2 ft 5 in. We are widening the doorway to 4 ft and putting in a built-in (therefore counter depth) refrigerator, so I figured that would keep the refrigerator doors from blocking the doorway when they are open.

Although I do love the idea of getting as big windows into the space as we can, the reason we have the upper making that turn is that we are going to have an appliance garage under it to put my food processor, blender, and stand mixer. I didn't want them to be too far from the range since I will likely be using them either right before or right after things come off the stove/out of the oven.

The long walk between prep and fridge would bother me more than the door to DR being blocked when the door is open. I would split the pantries to get the fridge closer to the prep area because that extra long walk isn't necessary. I'd want my kitchen to be more efficient. Organized pantries should allow you to keep the items used most commonly during cooking in the pantry next to the fridge. Use the other pantry for more snack items, cereals, crackers, overflow, etc. Anything that isn't normally part of cooking.

And I would just do an appliance garage under the straight run of upper cabinets and have bigger windows. But I'm a bit of a window addict so I almost always choose windows, lol.

While we're talking about how I'd do it if it were my kitchen. I'd put the microwave in the beverage center and put the wall oven under the counter so I could have a bigger window on the other side of the sink, too. :) This would also allow those who are heating drinks or snacks to do so without entering my prep space.

Just some things to consider. It's your kitchen and it needs to be designed for how you live. I would go nuts with your proposed fridge location after awhile. But you have lived with it so you don't appear to mind it. If it works for you, ignore me.
