First of all , A very congrats to you to clear the CA final exams..........I think u r in dilemma . Look Ca profession itself is a very wide & vast profession. If you put urself in mkt then you find that people expect so much from a CA. I think to fulfill their requirement is a ver big job & a challenging task for us. When you have a master degree so why u go for any other course . If you want to do something then go for CS or something like a pofessional degree which prove to be value added in ur profession.
So Best of luck for your bright Career & be Update yourself to be good finance manager.
