I did some organizing.
Left two chests - potions/regs.
Middle two chests - Armor, weapons, pouches, etc
Right two chests - random storage/loot
Anything in the right two chests is subject to recycling/smelting/etc. So, if you put anything in there that you want, make sure it's not there come recycling time!!
Back three chests. Dump regs/ingots/leather/etc back there. All raw materials. Any chest they will fit in is fine.
