I would balance the fridge cabinet wall by having the fridge centred between two narrower pantry cabinets as it currently feels far to heavy for your space. Alternatively, I would recommend having a narrow pantry on the left of the fridge with a full height cabinet with counter on the right with an upper cabinet above. This would help your space feel larger.

I never love open shelving in a modern kitchen they are dust and grease traps but I would hang horizontal glass front cabinets and paint that wall some awesome color ,run your backsplash up to bottom of window all across. If you have space make the island top larger and paint out the other wall of cabinets to match main ones. The island top could be something much different than the others

So you dont think we need bench top on both sides?

You could install racking for both sides of the room, toys & clothes that aren't being used can go into large plastic containers with lids. The two bikes could be hung from the wall or ceiling. And yes, anything that doesn't need to be there, move it on. There are so many hooks and storage options available that it would be very easy to sort this out and by getting a lot of it off the floor.
