Thank you very much for your numerous responses and the feedback so far.
The 3D view is, as mentioned, only roughly accurate and there are, for example, dark tiles at the back on the wall, one of the wall cabinets is a display cabinet with a glass front for variety.
As for the background: We are a young family of four. I would very much like to cook and prepare food together with friends and family in the future. I have attached the living space as a whole. The left door in the 3D view leads to the utility room with a little storage space as a pantry.
Next to the sink, I would have liked to have a tall cabinet with an integrated oven, but then it was too tight with the sink and the stove.
I see no advantage in integrating the sink into the kitchen island, so I would rather not pay an extra charge for the pipe installation. Not much is washed by hand with us; almost everything goes into the dishwasher. What is washed in the sink is then cut and prepared on the cooking island.
We did not integrate the stove into the kitchen island in the plan because a solution for the extractor hood would have to be found again. I already had experience at a friend's place with an extractor hood integrated into the stove; however, it did not convince me. I also do not like an overhead extractor hood because then there is a device hanging in the middle of the room again.
In my opinion, we therefore do not really have many options.
But I am happy if you can convince me of something better
