Don't know where anyone got the idea that BNCs made for RG-8x we 75 ohm. I worked in the tv industry for many years and we used hundreds of BNCs that were made specifically for 75 ohm video. By the way, RG-59 not RG-79.
While you are entirely correct that there are 75 ohm and 50 ohm BNCs, the difference DOES NOT MATTER at HF, because the connector is such a small fraction of a wavelength and the difference is small. 75 ohm connectors were important with analog video because of the smearing of very fine detail in a high res image, and because studios do lots of patching and routing.
