What's why I asked the question. The HDW5231R-Z is a very popular camera and there are many experts on this forum but no-one seems to be interested answering this question.
My experience has been that if you give
Blue Iris the proper ONVIF admin username/password, when you click Find/Inspect, the 5231 will provide back everything that BI needs to properly configure everything. At least that's how it worked on four of my cameras... Video, sound, zoom, ... everything worked/looked/sounded in BI the exact same as the web UI on the camera.
Here's what a normal Find/Inspect looks like on my 5231s.

Two of my 5231s came from a vendor other than Andy, and for whatever reason, when I logged into the cameras the first time (and it has you reset the admin password), it did NOT reset the ONVIF admin password to be the same. So when I typed the password into Blue Iris and clicked Find/Inspect, it came back with completely different results than above, and the two cameras behaved differently with BI than the other cameras.
Here's what a
failed Find/Inspect looked like on my 5231s:

So my experience has been that as long as BI can successfully Find/Inspect the cameras, everything works perfectly, so I've not attempted to find "better settings". I'd imagine most folks have had the same experience.
But since I have no experience with "better settings", I would normally not reply to a thread like this. It's not from "lack of interest", it's from "lack of experience" (with what you're asking).
