Remove the pass-thru and table and put in more cabinets. The breakfast set is eating the room!

You say none of doors can be changed. However, if that were not an absolute, I would open the pass through, which looks dated, and make it a grand more "open concept" entry into your kitchen. Put nice moldings around it, then close off the skinny dated opening to the right of breakfast table, as it is a very awkward angle to enter this room. Now, you can put your refrigerator to the left of the stove area, where it feels less impinging on the entire space.

The area vacated by refrigerated can filled with additional pantry, or base cabinets and counter with floating open shelves, which are certainly popular now. Or dish drawers below, with glassed china cabinet above. ( My clients love the dish drawers as they no longer have to be lifting up heavy plates at their head level) I have done some amazing cabinets like this, but have not uploaded them yet to my page, but will try this week.

Put nice moldings around the backdoor and bedroom door as well. It will elevated them aestheticly.

Select a muted palette for your wall color. It makes a nicer transition for a room that is a pathway to a bedroom. Not so "kitcheny."

You will need to roll your curser over it, but the drawers hold my client extra sets of dishes. But the everyday dishes are also in drawers in the island.

Probably would remove all of visual clutter, and curtains and treat the kitchen more like "fine dining in the kitchen". It is the open concept, concept. It will work.

5 doorways in kitchen need some design ideas.
