DSLR versus Mirrorless Focus Differences
And also this snippet of advice in his other article to help low light focusing. Perhaps the Z9 also applies to exposure performance (?)

You have asked very valid questions. First off, what focus settings worked in your D850? I would work from similar settings and gradually bring in more of the options. I wouldn't use 3d when there is more than one object like bird in branches. Beyond that, I would recommend Steve Perry's ebook on the Nikon Focusing System. You might benefit from Thom Hogan's website bythom.com. I think too that you can go to Moose Petersen's website. He provides a list of the settings he uses on the Z9 for wildlife photography.
Auto ISO depends on your exposure metering selection. Matrix metering doesn't work well with a backlight situation. Center weighted might be a better choice. I found the D850 and Z9 to be similar in that regard.
