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

Here are links to 2 older threads that may be useful to you. The common suggestion is steer away from cool or stark whites with this stone. It might be worth seeing how 1/4 strength antique white usa colour looks with Frosty Carina. Or 1/4 or 1/8 strength beige royal?? This colour at full strength is suggested in one of the links. It also is paired with antique white on dulux colour wall.

The front of your home looks like homes in Las Vegas, Nevada. Are you more interested in a bathroom along these aesthetics? In Australia the bathroom you have shown would be a very common look. If you are staying in the home for a length of time, and your budget meets your wishes. Then change it to whatever you would feel more comfortable with.

@Kate Exactly, this is the one. @ausjoinery Yep, we have kids at home. Am not too fond of glossy finish due to finger print will be easily visible, but positive side of it is easy cleaning. @dreamer I was thinking about the darker cabinets too (Though am a white colour fan), awalnut brown or black or so on..
