I like the look of one size pull for everything. I also like one pull on a larger drawer not 2 small. I think its more natural to use one hand to open considering you will probably have something in your other hand and won’t open with both pulls at same time. If this happens frequently, as I think it would, drawer could become unaligned always opening on the favored pull. Here is the look of same size pulls on all drawers in our kitchen, do not have more photos yet but you can see island has larger drawers and all pulls are the same. They are 6” pulls I could have gone up to 7” but like the way it turned out. Also I like either all pulls or combo of knobs on doors and pulls on drawers like we decided. Hope this helps, your kitchen looks great.

I am not a designer but we are just finishing up our kitchen remodel. We chose two sizes for use. The smaller on uppers and smaller drawers and larger on the bigger drawers. I am happy with the way it looks. Good luck, you look like you are almost done and ready to enjoy!
