The FTZ adapter has no optical elements, so it shouldn't factor into the equation. Its only function is to position an F-mount lens the correct distance from the photo sensor. So, mount your FTZ on your Nikon Z-series camera, then attach your F-mount teleconverter, then attach your F-mount lens. Easy peasy.
If I read his question right, he referred to using a Z camera with Z lenses; not f mount lenses. So, based on that, I would think he needs a Z TC.
