IMHO we should start with nothing but some rags, and shortly after we escape find an armory, which enables us to get some weapons and equipment. it worked in BG2.
if the devs are worried about us taking mountains of gear with us, they could limit what we take by having it be dialogue with a chest.
you click on the chest and a dialogue box comes up. Let's say you're a fighter.
"you open the chest and find that your equipment has been stored here. in the chest you find a suit of your.... 1: Leather armor. 2: scale armor" etc (obviously it can be limited to some select choices)
"you also find your weapons" *insert selection from several weapons types*
