A photoshoot of what?
I had a professional portrait studio and had 14 lenses, generally used 5 or 6 lights - main, fill, kicker, hair, rim, backdrop, and had 20 or so different backdrops.
You wouldn't use the same lens to shoot a group of 6, to also shoot just 1 person. By the same token you would use one lens to shoot a head shot, and a different lens to shoot a full body shot.
For some of the on-location commercial shoots, I needed 2 assistants and as many as 20 lights.
My go-to/favorite portrait lens was a
AF-S NIKKOR 200mm f/2G ED VR II from Nikon, but it wasn't always the right lens to use.
Unless you know what you're doing, with only 2 lights your white background will usually be some shade of gray instead of white. That is because of the Inverse Square Law of light.
Inverse-square law - Wikipedia, the free encyclopedia
To keep the background white you'll need a couple of lights on the background. Another problem many have white background, is when it is lit well enough to be white in the photo, a lot of the light you don't want bounces back onto the subject. Part of the solution for that is to keep the subject 8 to 12 feet in front of the background. How far depends on how reflective the white background is. If the background is really reflective 20 feet in front of it may not be enough.
If you don't already have it I highly recommend the inexpensive book -
Light Science and Magic, Fourth Edition: An Introduction to Photographic Lighting
