I wonder, as far as RFI coming in on the USB cable itself, would it help to add some RF bypass capacitors from the USB data/power lines to ground within the HF+?

It seems like that would essentially short any stray RF to ground at the connector, while allowing DC signals and power to remain unaffected.

Or would that distort the rise/fall of DC transitions on the data lines?
USB signaling rates are, in fact, RF rates. Any that effectively suppresses RF
will also suppress USB.
