Ken Rockwell posted the 24-70mm S lens. The conclusion:
The Nikon Z 24-70mm f/4 S is a compact high-performance ultra-ultra sharp lens for Nikon’s new full-frame mirrorless cameras.
It’s tiny and optically excellent, so it’s the best lens you can get for you Nikon Z now. I’d not bother with an SLR lens on the FTZ, which is going to be bigger and have lower performance. If you’re going to use a Z body, get the right lenses for it.
