Did you already check this paper? (thanks to Maxime for the hint!)

Markus Ring, Sarah Wunderlich, Deniz Scheuring, Dieter Landes, Andreas Hotho: "A survey of network-based intrusion detection data sets", Computers & Security, 2019.

This survey is covered here.

I found it to be the most comprehensive survey of all the ones I looked at, it's also one of the few providing more than just a basic description of each dataset. Covers only network-based datasets, though.
