It depends what you regard as "standard".  The TV/CATV "standard" are
F-connectors, available almost everywhere the cable is retailed.  There
are 75-ohm BNC connectors available.  When I ran a TV signal
measurements unit decades ago, we had lots of 75-ohm cables with BNCs on
them and we painted a red ring around the connector body to distinguish
 them from 50-ohm BNCs.

Yes it foes if you want a shielded balanced line.  Just disregard the
losses and impedance mismatches.
