Based on my 5+ years experiance with the Liebherr French door refrigerator/freezer, I'd highly recommend it to anyone looking for a 36" unit. It's quieter than the Sub-Zero it replaced, well laid out, is very energy efficient and makes the best ice cubes (not the typical crescent shaped ones that stick to the rim of the glass) of any refrigerator I've ever had.

Can't help with those fridge brands but I have the BS 36" range and Miele DW too. I was going to do the Sharp microwave drawer but I really wanted a second real oven so I went with a Miele speed oven installed undercounter. The speed oven is also great when I don't want to heat up the whole 36" oven for something small. Have you considered the need for a second oven?

I have the Viking Pro CD with trim kit. The issues that exist with the Viking builtins don't exist with the standalone models. There are a few quirks (small freezer space), but it is working fine for me. Most of these quirks are more related to a CD FD configuration, not to the model itself.

The Vikings (D3 and Pro) are alleged to be made by Whirlpool -- who also makes the KitchenAid and JennAir CD models. Thus the guts are largely the same, but the accessories, shelving and skins may be different. Just wanted to point this out, because between the three there are many similarities.

Another vote for the Liebherr refer, love mine!
And the Bluestar range... if you cook like me, you are going to think you died and went to heaven :)

BlueStar now makes a free standing counter depth refrigerator at about $2900 in stainless steel. A link for it is https://www.bluestarcooking.com/refrigeration/36-freestanding-counter-depth-french-door-refrigerator-freezer/
