The problem with the american ovens is the depth. No microwave will have that depth so it will look pretty awful. Would recommend a drop down or drawer microwave under a counter elsewhere. We sell tons of KB6524PS from sharp that's reasonable priced Alternatively a GE Advantium with a drop down will give you tons of functionality and can be put undercounter (the 110V model ONLY though!)

I think its more important that the interior doors should match the interior style, than the exterior style (assuming your interior style is vastly different than the exterior). If its the doors I'm thinking, the interior door you like is a very contemporary/modern frosted slab door. Are the furnishings and finishes inside the house going to be on the modern side? The exterior door is very rustic/French Country/European, and goes very well with almost every other interior door on that page (the doors are mostly traditional), and works well with a traditional style interior, IMHO.

The older Gaggenau ovens are 27" wide. The current ones are 30". both are standard sizes. Mine is from the first group of 30" and the interior front to back will hold a 16" pizza pan, but barely. I don't know if the current model has the same conformation. They also make a classic 36" oven, though they have recently updated it. Gaggenau is one of the most accurate ovens on the market, though you pay for it. People here are happy with the side opening Bosch, which has a more accessible price. Bosch used to have the biggest cavity, but I don't know if that's also true for the side opening one. Definitely worth checking out. I'll say again, GE's ovens have a poor reputation. Uneven heating and other control issues. Look at the AR and BS. Before you get too set on any kind of flexible surface induction cooktop, do read the manuals really really thoroughly. There are limits to the "anywhere you want", the amount of power delivered, etc. It's very different technology to the standard inductor rings--I didn't realize that's what you were talking about before--and I would definitely not go with Viking on that. Not without a lot of other guinea pigs reporting that it's great and that the customer service is also great if something fails. If you think you really want it, AEG (I think it's now part of Electrolux) and Siemans (BSH=Bosch, Thermador and Gaggenau here) are the companies that have been in it longest. I don't think AEG is offered in the USA. That leaves Thermador and Gaggenau to look at. You might like the new Gaggenau 36" which has two "freedom" panels on the sides and a big multiple ring in the center. I think you could do three of your big pots across--do read the manual to be sure, but I think you can power share the front and back zones with one big pot in the middle of a freedom, which I think is four oblong inductors. But, again, you pay for it. Modern dishwashers are very different from your old Kenmore. They're designed for energy and water savings first, and cleaning second, ease of use third and drying a lag behind. Most people love Miele--mid-range on up. It's not as big, but genuinely loved. Most DWs are pretty good. Find one that fits your loads, and it'll probably be okay. Most of the work now, is done by enzymes in the detergent, rather than heat or power, and most machines require rinse aid (surfactant to loosen the water) for drying. Not spot prevention, but to actually get your dishes dry.

I would have it match the house body color. Matching it to the garage door would be my second choice. I would never paint it to match the front door to avoid highlighting the door.
