I'd go with the NUMA POPCNT version, but to be sure make a multithreading test with all the x64 versions with this program: https://chess.massimilianogoi.com/download/buildtester/ .

If you share here the result you would help, thanks.

In CFish, in the engine parameter:
Pure is pure network score
Hybrid is a hybrid ... If the score is up to +5.5 then the network is used. If higher, it is a classic grade.
Classical - well, it's clear from the name
