I just bought a used set of socket wrenchs. It has both 6 and 12 point
sockets. Why?


I am guessing that 6 is stronger and 12 can be used on square heads, but
neither of those seem to justify having both. Is there a better reason?

There are 12 point bolts. Ford has used them as head bolts and for some
other applications for example. If you run into one and have only 6 point
sockets you will be out of luck.
