One thing about worsted weight yarn is that the socks may be too thick to be worn comfortably with shoes. So that's one thing you might want to consider.
I can't think of any worsted weight yarns that are specifically for socks. There are some DK weight ones that I am aware of. I think Opal makes one. In worsted weight you should look for superwash yarns. Cascade makes a superwash in worsted weight.
