Nikon Nikkor Z 28mm F2.8 Q&As

Hi everyone. I have a Z6II with the 24-70 f4 and FTZ with a good selection of F mount lenses. For my 2nd native lens, I was thinking of getting one of the entry-level prime lenses like the 28mm f2.8, 40mm f2, 50mm f2.8. I have found that there are also 2 packs of these lenses with a Speedlight the 40mm with the sb700 and the 50mm with the sb5000. I have been able to use a loaned SB700 which is fine but am wondering if the SB5000 will work better and more like my old speedlights have worked on...
