It sounds like you are getting a package deal on the Wolf/Subzero grouping. I don't think you are making a horrible mistake in any of your choices. I haven't had either a Wolf or a Subzero for many years. They have a good reputation. Both have had challenges in recent years. Hopefully, the challenges have been corrected. The Wolf ovens have had a problem that has been covered at GW quite thoroughly. Hopefully, it is fixed. Just do a search to familiarize yourself with delamination.

You didn't mention ventilation. That is a major appliance, too. Many people will treat it as an afterthought. Don't be one of those people.

I can speak to the Bosch dishwasher. It is a fine unit. They have a wide range in design and price. I don't think you need to spend a lot of money for the top of the line. The middle of the line will do the job. I don't put my fine china or my crystal in any dishwasher, even my Bosch. So, why pay for the extra cycle features that you won't use. On and off are sufficient.

Do be aware that many installers will not install the drain hose correctly. This is through ignorance. Read the installation manual or look it up on line. The drain hose can't have a kink in it. Also, it needs to be run through the cabinetry and attached to the plumbing a particular fashion. If it isn't done correctly, you will get nasty smells and poor drainage. Have your plumber involved.

As with any dishwasher layout, some people have problems with the layout of the Bosch (their dishes don't fit). I would strongly encourage you to take some of your dishes (plates and bowls) and silverware, along with some other items you would wash in the dishwasher, and see how they fit. I have a Bosch 800 and like it a lot, and my dishes fit great, in a particular location in the dishwasher (I can fit a ton of them across the back of the bottom rack, but the tines in the front of the bottom rack would be too skinny). The DW cleans my dishes extremely well (better than any other dishwasher I've ever had anyway). We went with Bosch rather than the oft-recommended Miele because for the hidden panel/paneled front dishwasher, we weren't willing to spend the extra $$ on the Miele.

We have a Bosch dishwasher going in. I can't comment on function yet but will second that there are what seem like pretty specific install instruction for the electric and plumbing you or your contractor will need to be aware of.
