Hello Gurpreet Nice to see you in this beautiful platform. As kitchen is a main part of your home,therefore it should be neat and clean. One should clean their kitchen once in a week whether your own or commercial.Choosing flooring for a kitchen is a very important decision.I think hardwood flooring would be nice options for commercial kitchen as it is easy to maintain. Porcelain and ceramic tile would be an ideal for commercial kitchen.For better advice you should contact with interior designer.

Visual below is similar case like your preference of using wooden texture laminate with black counter top & lighter floor. Check out misty oak, pine, birch... in laminates!

The main sink is right on the corner -- only one place to put things down. Behind the sink is not a great option. Other sink -- prep sink? hand-washing sink? bar sink? seems to be too fancy and not very practical for a kitchen space. Save that kind of sink for a guest powder room. Any sink in a hard-working kitchen needs to be flexible and purposeful. The exhaust fan above the cooktop seems too high up and not wide enough. Trust me -- mine is not wide enough, and I wish it was, but at least it's not too high up. I appreciate in this sleek, modern design, you want a very low profile exhaust fan. But -- you need the capture area to be wider than your cooktop so you can capture all the grease, steam, and smoke. One advantage you have is that there are no cabinets there to limit the width of your exhaust fan -- so widen it up. It's a must in a hard-working kitchen, especially one with a somewhat open floor plan. I don't know how you will use your kitchen or what the rest of your home is like. You may value a sleek, beautiful kitchen way more than a hard-working, efficient space, in which case, most of my comments are lower priority.
