@Sharon D, I have had no issues with steam damage to the upper cabinet. I don’t open the oven full force right after shutting off from habit, mostly because I don’t want a face full of steam. Occasionally the upper cabinet feels slightly damp right after, so I just wipe it with a kitchen towel proactively. It’s been a year since install, and everything looks new.
I did buy the Wolf pro style convection oven btw. I have had zero problems with it. I don’t use the self clean (I never have in any oven I’ve owned), so I can’t say how it would perform if I ran that on a regular basis. Every other week or so, I make a loose paste of baking soda and white vinegar, remove the racks in both ovens, and coat the dirty surfaces with the paste. I run the steam oven on 190 degrees (steam only) for 30 minutes, and the convection oven on Proof for about an hour. Then, wipe down. The ovens are always sparkling clean after that. If the glass is dirty, I use a magic eraser, which cleans it up quickly. Good luck with your CSO!
