May I suggest a cap of your pavers on the wall and the a slightly darker gray that relates to the privacy fence beyond? That way horizontal surfaces and vertical surfaces show similarities and blends/blurs the separations?

I love a QUALITY paint job. Few people know the ins and outs of a quality paint job but, a seasoned painter for INTERIORS will have many techniques and processes to dial up the end result. I love my painter and I listen closely to his advice and he is so expert (40 years) and good that he makes it look effortless. BUT IT'S NOT. Will find and post favorite picture of painted trim here. I think the secret is style and proportion of trim and then the quality of the finishing. Did you know most paint curing really needs 2 to 3 weeks to set up as a really good tough finish? "In a hurry" is the curse we mostly experience for improving interiors. I wonder sometimes how different things would be if people took the right amount of time to do things in the time frame related to that finishing task!

Before and after!

I'll say it straight out -- I personally don't think the style of fence matches the style of house . But not painting it makes it even more obvious . Maybe you need a new friend haha . Me -- I'd render the wall , and paint in an English Cream , AND do the 3 gables and the boards above the garage door and any other trim in the English Cream too , to tie it all in . IF the bricks were still available , I would have gone down that route , with the rendered fence pillars ( and gables and trim ) in an English Cream , or possibly the pillars in the same white as the house bits , but generally I'd try and go a bit closer to the brick colour than 'just' a white . It's workable , and almost anything would be better than leaving the blocks as they are IMO .
