In the dmesg output I included:
mpt3sas0: LSISAS3008: FWVersion(10.00.00.00), ChipRevision(0x02),
BiosVersion(08.25.00.00)

I suspected that was the case, and tried running elrepo's "kmod-mpt3sas"
from their testing repo. C7 has version 04.100.00.00, while elrepo's
appears to be 13.100.00.00. That didn't change anything.

Haven't asked yet, since the same firmware produces different behavior
on the two OSs.

That'll be one of my next tests.

I'll look around for that, too. No vendor tools are installed, currently.
