One thing to point out is there are big differences in card performance based on card size. Almost all 64GB CFExpressB cards have a low minimum sustained write speed. The ProGrade Gold card you tested is the fastest – the 1TB card – and smaller cards are much slower. The Canon R5 is a very good camera, but file size is what drives performance. The larger files of the Nikon Z7ii and Z9 are more demanding on card performance. Likewise smaller files but faster frame rates have a similar impact – more data to be written per second needs a faster card. The advice you gave is good – make sure you match what and how you use your camera to card choice.
