My advice is to practice a lot while standing! :) You're right that it can be a different physical approach. I also tell students to use their strap while sitting. And adjust the strap so that the guitar is in the same position regardless of whether you are standing or sitting.

I explain & demo this at about 3 minutes in this lesson.
