How does cellular versions help me? Is it only if I forget my phone? Will it work with my same number on my phone?
 
It does use the same number as your phone, other than Family Watch (for kids).

It’s useful if you don’t have your phone with you - accidentally or on purpose. I know some people like to run with just Apple Watch & AirPods, for example, and leave the phone at home.

Personally I do have Cellular active on my current watch, but I get a discount from my carrier so it only costs $5/mo. To me, the benefit probably wouldn’t be worth $10/mo but “just in case” I forget my phone, it’s occasionally handy. It also was helpful when I smashed my phone while on a trip; let me call people etc. until I got home and had the phone replaced.
