This is just my personal opinion, so nothing official here.
I started out as a freelancer trader on this server, and that's how I played for ages. Actually, that character still exists here as well.
Actually, the key thing for traders is quite simple. Don't allow people that aren't part of a corporation to actually fly the biggest ships. Now - when I'm saying that, I'm referring to actual faction members, or members of organized unofficial factions (aka ships with real tags). Then it's a case of who cares what the smaller indies are flying, since they're by design restricted to smaller ships.
Oh, wait - that sounds suspiciously like faction right #5 for restricting cap ships, doesn't it? Hmmm - wonder where I got the idea? :P
There's certainly no reason to actually restrict cargoes at all. Just make sure that the people flying the 4,500 plus corporate cargo hold ships actually are corporate pilots and quite honestly, not the powertraders that don't care about RP.
