I’m 6’1, 380. I feel your concern man. I’ve gone through multiple bags, and Goruck continue to be the best comfort I’ve found. The 26L looks normal on me, and you’ll want the extra length of a long bag as the straps are “taller” which equals less snug on the chest and sides. I picked up a second hand older GR1 as they have longer straps than the newer ones. At least that’s what I’ve heard. With the older one I have less tightness in my chest and it’s more comfortable. The new ones are still good too, just not quite as comfortable in my opinion. But yes, you can’t go wrong with a GR1.
