In this video, Ricci mentions the overheating problem, and the 2 cards above he recommends are indeed, Delkin Black and Prograde Cobalt.
There's a fair amount to absorb in this overview, but I do find it hilarious how he's neatly eclipsed the talking heads... and might even silence a few trolls. More seriously, Nikon appear to have woken up the need to get out timely feedback and assessments.
It is probable, Nikon has made his semi-independent video channel as central part of his job description. He's built up a solid reputation over the past 2 years.

Those are the advertised max write speed on the Sony tough cards. What you want to see is the minimum sustained write speed which Delkin Black have advertised to be 1405 MB/s. And i remembered someone have tested the prograde 650GB cobalt to have about 1300 MB/s minimum sustained write speed and Delkin Black 512GB to be 1430MB/s. The unknown one will be the Sony Tough CFexpress Type B cards.
The problem with sustained write tests is that it depends on temperature management; CFexpress cards slow down as they get hot (there is a protective function integrated into the card) and thus how the speed changes over time depends on the temperature management of the camera and may depend on environmental conditions as well. I think for sustained write speed the tests need to be done with the actual Z9 camera.
