I'm not an expert but I do live on the coast. IMHO, there's more than one way to accomplish the coastal look and feel and still have it be appropriate. I personally prefer touches of darker furniture and/or accents to add some contrast and grounding to all the 'floatiness' of the typical whites and light blues. As far as espresso furniture goes it seems to be a more recent trend, which may explain why it wasn't common years ago in coastal decor, but I'm definitely seeing it used as an evolving, updated version of coastal decor in the PNW. I personally have an espresso dining table and chairs...I'll be adding short, white slipcovers to the chairs for our 'summer' look, and I think it looks great with white slip-covered sofas and white kitchen in our great room. We have a few other elements that tie in the contrast and it all just works. The photo and link below give at least a rough idea of what some darker elements can do for the coastal look for those who prefer it...

What's wrong with the downlights you have? They seem appropriate for the locations. Maybe you need to just re lamp them. What type of bulbs are in the can lights? R series bulbs are usually installed by builders or electricians because they are the very cheapest bulbs they can purchase and should not be used in a home like yours. PAR bulbs even in an LED form will provide you with better quality light to highlight the gallery you have on the second floor. BTW you were ill advised on the lighting for your kitchen The barn doors for the pantry should either be painted white or stained to match your chairs The bead chandelier, though charming, is much too small for over that table and for this kitchen. Some type of linear chandelier would have been a better choice IMO I would have recommended you select the same style chairs for the table that you used at the counter The pendants over the island are too large to be hung that close to the edge of your island and hung too high over the island (for some reason in your photo the pendants don't seem to be the same distance from the edge of each side)

If you are going to replace the light fixtures already ... have you thought about doing something really cool with some accent lighting along the wall? It would be modern but Lifx and other companies have some cool solutions for lighted tiles that let you set the color of the light (or run neat patterns across a swath of space). When I see this space I think, "Keep it clean & you won't have to dust up there very often" but I can understand wanting to do something interesting as well.
