I think the AC-9260 you have should be a decent sniffer. The (yet
unreleased) follow-up hardware is even better, but this one is fine.

Just remember to load with amsdu_size set to the appropriate (maximum)
A-MSDU size you want to capture.

I was looking at the firmware now and ... well, I want to really test
this to understand what's going wrong, because it really *looks* like
even the recent ones should be supported natively, at least as far as
I've looked now.

AC-9260 should be fine, as far as Intel is concerned. Also make for good
sniffers, in my experience, we use them all the time for that.
