I'm not sure about battery voltage sense wires? Is this related to the TriMetric connections?
And I don't know what diversion load wiring is.
Voltage sense wire has nothing to do with Trimetric, but is a "recommended option" for Morningstar controllers. I think you need it.
Load diversion was, I believe, a tongue in cheek comment. Those are necessary with wind turbines, but in solar it's optional.

This is what we preliminarily came up with - I mentioned that it seemed like others were putting fuses on each panel, but I never saw a discussion of why
Not on "each panel". There was a discussion, and the Handbook by Bussman-Cooper was quoted, which handbook said, on the page 5, that if Isc of parallel array exceeds the conductor/string rating calculated as 1.56*(PV Isc), string fusing is necessary:
