If you have a Nikon ZR, Z6III, Z8, or Z9 with current firmware and NX MobileAir, you can now directly push still photos through your mobile device to Adobe's frame.io service. Images on frame.io can be immediately processed using Lightroom, or shared with others (e.g. your client).
Once NX MobileAir is paired with both your camera and frame.io, you basically have "hands free" transfer of images into the cloud, either automatically or by selecting images manually on the camera for transfer. This is simpler to set up and less fussy than using an FTP server, though because a third party is involved, there is a cost to using it. Frame.io has a free 2GB storage plan for Creative Cloud users, but if you're really going to use this method to upload, process, and share photos you probably want the US$15/month plan that includes 2TB and a number of other useful features.

Nikon's first implementation of frame.io integration worked with videos, but I didn't notice when they updated that to handling stills. The current NX MobileAir documentation describes how to set things up with your frame.io account and then use it.
You can also do a similar thing using Nikon Imaging Cloud, but I find it to be less seamless than the NX MobileAir version.
