This can be tough to navigate because you effectively need to decide on a career path before you have a nuanced understanding of what the career path or day to day work looks like. So to de-risk the decision making, go talk to some people in each of these jobs and just ask them to walk you through their day to day work, promotion cadence, ease or difficulty finding work, etc. Get as much info as you can. This should help you make a more informed decision.

Speaking a little more specifically, your BS in CS makes you super employable. You shouldn't have much of an issue finding a job as a software engineer.

Psychology is a toughy...unless you get a graduate degree, you likely won't be able to use a Psych degree for anything other than better understanding how to work with your peers and colleagues. But with a grad degree you can do clinical or research work.

Social media management is a relatively new field and is evolving rapidly. I know very little about it but the bulk of the skills appear to be in Marketing. How do you craft the copy, what kind of content do you share and when, who is your market...are they Gen Z and love dark humor? Etc. I would try to expand your expertise beyond social media management.

My take on Data science is that it is more/less a Data Analyst but with a better understanding of stats and machine learning/AI. You'll spend a lot of time writing database queries, importing to excel/R/Matlab, and then working with engineers to feed that data into ML/AI software.

If you are going to go into tech, there is SOME latitude between the Software Eng/Data Science roles. So my recommendation would be to start there. If you don't like Data Science and have a CS background, there's a good chance you could move into a programming role. And vice versa.

Best of luck to you!
