I can tell that you are not writing from Boston! :>) Well, if you want white cabs, use your trim paint in a gloss. If you need to fill with molding from the top of the cabinet to the ceiling, it will match. I love blue and white in a kitchen.

I would personally stick to white cabinets... I know, not very original... but I think white works best with timber benchtops... and black/white/timber is a fail-proof/timesless combo imo... But if you wanted to inject a bit of colour... and based on your coastal theme description... then I would suggest maybe duck egg blue?... do a search of "duck egg blue kitchen" in photos on Houzz AU

It may be a colour specific to the manufacturer of the cabinetry. If you'd like it to match a paint colour exactly take one of the doors to a paint shop to be colour matched.

Hi. If this could be of any help, you can go on Caesarstone website and select the stone you have chosen from their list (Frosty Carrina) and check the page. On their website, they have lots of examples of kitchen/bathrooms etc. for each stone colour, usually at the bottom of the page. This may be inspiring.
