I like your tiles OP. I think the wood grain look is neutral enough to have almost any colour units that you would like.
If you are having wooden units, don't be afraid to push the boat out on colour a bit - they can always be repainted. I went for something a little more "out there" for our island after getting inspiration online, and it makes me happy every day.
I love shaker style cabinets and don't find mine hard to keep clean honestly. Matt for sure for me.
Laminate worktops are fine - we have a newly installed laminate worktop in our utility room and modern laminate is much better than the stuff from the 80s and 90s - but we put quartz in our kitchen and it is fabulous... It lifts the whole room and you can tell the quality in finish a mile off.
We have an integrated microwave above our integrated oven and I love it. Would not go back to a dusty greasy countertop microwave.
Ditto to integrated bins. Our ones contain any smells perfectly, you would not know they are there.
Consider extending your quartz work surface up the wall behind your hob, and onto any window sills also.
As for stainless steel or composite sink - I've only ever had stainless steel so maybe can't comment on the differences. However in our new kitchen our sink is undermounted which is a very sleek look.
Induction hobs are fab. We changed from a gas hob that I hated - so dirty. The induction hob is fast, easy to cook with, and cleaned in one wipe.
