You can use a SNA for quick and dirty tests, comparing a known, high

Agreed. That is why I was surprised when someone said a scalar one was
more accurate.
The only regime where they are used today, AFAIK, ia at frequencies above
those practical for VNAs, over 40 GHz or more.
Agilent sell a VNA for 110 GHz. At $691,437 for a 4-port model, I
don't expect Agilent sell too many of them! If you buy all the
options, it will be over $800,00.
