I think your inspiration photo is beautiful and those ideas would apply nicely to your kitchen, especially the marble-look quartz countertops. Though with dark floor tile, I wouldn't do the full farmhouse sink and pure white backsplash. The brightness might be too contrasting and make your floors look dirty by comparison.

You need an electrician and to add about 5K worth of lighting. Start with under cabinet LED tape lighting.

I would seriously rethink doing Viking appliances. Do some research as they have been nothing but trouble for most people in the last 5-10 years. Check the Appliance Forum.

The money you save on replacing and repairing Viking appliances you can spend on better lighting :-) Seriously, Viking makes terrible appliances. You will not be happy. Look elsewhere. IF it were me I would go with Bosch or Miele depending on budget. Wolf/SZ is expensive when you consider their oven is a problem with their blue enamel chipping- so you can do a Wolf range top and get a different oven.

When I changed out my flooring from white vinyl to hardwood, it took me a few weeks to adjust to the change. The hardwood is natural, so not so dark. I love my undercabinet lighting - so definitely do that - best and favorite change. My sink is a "short apron" Kohler Whitehaven which can be installed on a standard sink base cabinet. It is just as deep inside as the "tall apron" style. Do be sure you like the look of the shorter apron - see it in a plumb supply shop if possible. The Kohler Vault which is stainless also comes in a short apron style. Kohler Whitehaven is on backorder right now, but since you haven't started yet, you can wait for it if you like it. Subway tile that leans a bit cream rather than ice white usually works best with oak - but it also depends on the cabinet stain tone. The tile in the inspiration pic looks slightly creamier than the countertop - as does in my kitchen too, though there is some cream in my countertop:

This is also the time to consider any layout changes. I would be incline to move the stovetop to the exterior wall - then you can vent and do a stainless hood. The pretty hood is probably one of the things you unconsciously like about your inspiration pic. I would not let the stovetop get too close to the sink, and there might not be room, but you would get much better venting. It is possible to stain a wood hood to match your cabinets - I did that, but it can get expensive compared to a stainless hood which would still be attractive.

wow turned out great!

You changed the ceiling too! Very nice job!

What a transformation!
