With such a large house I think it would need some other darker colour along with white to help "ground" the look. Also, as mentioned above, pure white on an exterior looks very glarey - surfmist would be perfect. I would strongly suggest getting a colour consultant to help with such a large project - and get some mock-ups done with different colour ideas.

Looks like your current paint is matched to window frames. Are you will to change or paint the frames? I would suggest professional painter. If not take the metalwork to dark grey. If windows changing maybe a warm white on walls

As soon as I see greys and off-whites as main colours , without something to add that Wow , I sort of wonder Why , but thats just me . No-one is offended at Charcoal , it ties in with most colours , its safe , but it adds to most overall schemes . My only real worry with charcoal is that it may get to be what Mission Brown or Forest Green became -- so overdone and tacky that everyone hates it ! A violetty blue , or bright red , or sunshine yellow is more polarising , and natural timber or stacked stone are outside some peoples budgets , but I always like to add something that is just a bit upmarket or bright or unexpected . Your place is sounding like 80% of new builds , whereas a bit of thought and $5k more could give it that extra attention IMO .

Firstly , you want something that you like , that suits the area and the climate and the vibe , so some of our suggestions are just guesses , modulated by our preferences , so take this more as a discussion , not a set-in-stone outline . Normally my ears prick up when I hear someone say they don't mind something a bit out-there , but I don't think this place wants to be or needs to be -- I'd embrace the era , and go with a 50's soft blue or apricot or mint green . The base boards then could be a more mainstream blue or orange or forest green -- not super bright shades of those , but about 3 times the brightness of the main tone , not 6 or 8 times , if that makes sense . They'd all look good with the white trim , and I personally would have gone for a stronger roof colour , but its pretty neutral so its easy to work with , and won't offend anyone haha . And the fence -- almost certainly a charcoal black stained wooden fence . Within 6 months , as your house starts looking attached to the site , so will the fence fade and weather and not look 'newly done' .
