You can hit a girt to do hanging, if I was to drywall again why add the expense and fire potential, this is why they make metal studs. Most supply companies offer a liner panel as an option.
There are a few things a guy might screw up but personally have all free standing furniture. What are the girt elevations? Parts of many buildings are done differently, with deep rib sheeting can span 8 ft on sidewalls. Mine are hanging with a coupl screws per sheet, if I was in super hi wind might screw them up tight but can remove to run utilities behind easily.
A pallet jack is pretty easy to store, allows it all to be modular.
It either hangd from the upper girt or is on wheels or can use a pallet jack.
