I agree 100% with the idea of using connector savers. When I sold for HP we always recommended it as it would cost thousands of $$ and lots of lost time to replace a connector on their VNAs. A simple connector saver costs little.
As for what to use, completely up to you. SMA male (to mate with nanovna) to whatever connector you most often use. Buy 2....or 4 (spares) and you're good to go.?
RE: Calibration. I recall reading a post suggesting doing a cal across the full span the nanovna covers. I'd think it would be better to cal just over the frequency span you intend to measure. With the limit of 101 measurement points I'd think this would give a more accurate cal.

Hello,
What was your solution for sacrificial connector?
Most of my devices are bnc/UHF connectors, so maybe sma to bnc?
Cheers!
