The latest Sony cameras with the dedicated AI driven AF processors are at an unmatched level in non stacked sensor cameras so far. But, to get that you need to get an A7RV or one of the new A7CII or A7CR cameras.
Can you link us to the testing you've seen on this specifically against the Zf? Curious to see it. I was not that impressed with the A74 or A7R5 AF granted I was mostly shooting birds.
Just do a search on Sony's new AI driven AF processor. The A74 doesn't have it, but the A7V does and there is notable improvement. neither of these cameras is orientated for BIF applications. Neither is the Zf. I doubt many will buy the Zf to do BIF shooting. That is the realm of the stacked sensor cameras. The Zf will also not be a good platform for BIF for the same reasons. However, the benefits of the AI AF processor are very well tested and documented out there. They show that the AF performance of the models that have it approach and even exceed the stacked sensor cameras in many circumstances. Notably the predictive capabilities that greatly increases initial acquisition, re-acquisition, and tracking performance with humans and other subjects. It is amazing in that regard.
As a simple example the Sony AI driven AF can instantly calculate where the eye is on a face even if the eye is hidden by sunglass and other objects. It knows the shape of many subjects and can calculate the eye position. It is much less likely to be fooled int thinking black dots are eyes like some other systems. That coupled with advanced motion predictions make a huge improvement to AI. The Zf has none of that.
A direct comparison to the newly released Zf has not been published yet. They will surely come. However, there are a number of good of reviews out there that do show the Zf AF in action. It is a meaningful advancement from the uncompetitive Z6II/Z7II AF performance. But doesn't approach the level of the stacked sensor cameras even though it implements much of the workflow. The Sony AI/AF processor equipped cameras do in many circumstances.
Here is a nice short video that shows the improvement over previous generations of AF in even when compared to Sony's already industry leading AF.

It is all out there if you care to look.
