Since your man purpose of studying further is to get into a higher paying job I would suggest you to make a list of all the courses that you are interested in to start with order them based on your interest look up on glassdoor or payscale websites, the average salaries in that field Lookup universities that offer the courses and attend a demo class if they offer one Take free or paid MOOC’s and check if it is something that interests you. And then zero in on one of them. Also do you like what you are working on now? Or are you looking for a change? You can decide on a course based on your plan.
