I would say the first is better (especially if you add a comma: "I had two options, of which I chose the former"). This is because, I think, you can rearrange it to be, "I chose the former of two options."
I can't rearrange the second sentence into a structure like this because the "from" doesn't work: *"I chose the former from two options"? It could be made more euphonious if you made it: "I had two options from which to choose. I chose the former."
