There is a section in the thread below, which covers storage needs and how to organize:

New to Kitchens? Read me first.

You don’t have room for that sideboard. You need a minimum of 36” around a table for peole to scoot past someone seated to reach their seat and occupy it. 48” is much better, and allows someone to not have to scoot sideways. Then you need an absolute minimum of 48” between the table and island for traffic with someone eith something in their hands, like a platter of hot roast beef. 60” is much better. There is far less risk of dumping the hot food down the back of someone’s neck to burn them.

Your kitchen wall could be extended doen further towards the fridge to occupy some of that blank wasted space, and the whole kitchen could follow. That would give you more room for the eating area that you need

A frig needs some space next to a wall. Or the wall needs to be cut back so your left door opens far enough to remove bins. A sink back-to-ack with the range create a bump situation when two people are using them. 42" drawers on either side of the range can be a choice I'd favor. A single bowl sink is my preference.

Post a 2D floorplan because I see a lot wrong with this layout as is.

Start by where do you intend to prep? One usually preps to the side of the sink but you don't seem to have enough room on either side of the sink.

I agree about the sideboard being too large. I would extend the cabinetry from the kitchen into the dining space. I'd also ask myself if the table and chairs are truly necessary if you had an island large enough for seating. My family eats around our island 99% of the time.

Definitely post a 2D drawing that is to scale.
