Thanks for the well-worded clarification Stan. I think I’ll go with
STMCubeProgrammer since I already have too many other custom drivers
installed for FPGA tools and dev boards.

I think either version works with nanovna-app (but I don't remember for
sure).
DfuseDemo and nanovna-app require the driver that shows up in Device
Manager under "Universal Serial Bus Controllers" as "STM Device in DFU
mode". This driver needs loaded into Win10 or Win11 if you haven't already
done it, and is part of the DfuseDemo package.
STMCubeProgrammer requires the driver that shows up in Device Manager
under "Universal Serial Bus Controllers" or "Universal Serial Bus Devices"
as "STM BOOTLOADER". This one is the standard driver in Win10 and Win11.
If you do not already have the driver set up for nanovna-app and
DfuseDemo, I recommend using STMCubeProgrammer, which you can download
from the ST.com site - simply because you don't need to deal with windows
driver issues.
Regarding the MS vs SI version: they both use the same firmware build.
Just go into the Config - Expert Settings menu and select the SI or MS
mode. [At one time DiSlord and others were making separate builds for the
two, but the only difference was the initialization of the processor mode
parameter.]
