85 ohm RCA cable matched with 75 ohm or 50 BNC connectors?

the shield mates first.

Thank you everyone for sharing. I synthesize:
For unbalanced audio BNC has the following advantages over RCA: locking, higher reliability
For unbalanced audio connector impedance does not need to match cable impedance. This only matters for higher frequency signals.

I can add to summarize it all:
Almost any connector type is better then RCA, because RCA is the worst connector type. The only good side - it is cheap (and popular in audio).

I see these for USD25 a pair, so not a cheap option.
Cheap is the main reason for the RCA
