When autofocus was first introduced with DSLR cameras it was a game changer, especially for bird photography. It became more capable and refined over the years but the new subject and eye detection capabilities takes wildlife photography to a new level. A 2022 mirrorless pro $6500 camera should significantly outperform a $3300 DSLR D850 released in 2017.
For me it comes down to the available cameras and the available lenses as both are needed. For macro the speedlight options can also be a deciding factor. Add in video and other factors come into consideration for the photographer. In terms of the best combination wildlife, macro, and video capabilities my vote goes to the Canon R5 C camera. Selling for $4,400 it is a relative bargain when compared to the Sony A1 or Nikon Z9.
