I recently got a message that I can update my wireless settings. What is the benefit of doing that?
It is updated info on features with Verizon and what servers or settings to use for most efficient use. You should generally always accept. It is not an iOS update. Here is an in depth explanation.

The biggest thing is updating the list of towers. Back in the day you could update phones by dialing #228, but with LTE phones that doesn't work.
