I am also using the Zf mostly to take pics of my hyper active 1.5 yo daughter and I can totally relate. I've sold my Z6II for the Zf, had both for a few weeks so I could compare them a little and found the Zf superior mostly in the subject detection department...but as for AF accuracy, there are issues with the Zf, no matter how much hype is spreading online. I dislike most online reviews for this exact reason...they are made and uploaded for clicks, often by inexpert people, and very few reviewers have taken the time to test the AF in challenging conditions with multiple lenses as you did before uploading their "content". On top of that, they don't want to upset Nikon, I guess...the result is that online reviews are mostly unreliable, and what matters ultimately is user hands-on experience.
