I am unfamiliar with your school system I think. Final year of college / university? Do you have a specialization in your major (graphics, machine learning, embedded, networks / security - something like this?)
I’d go with something from the specialization if you have one. If not, just something that interests you.
I don’t think this comment ahould be erased. OP’s reply is good imo and makes it obvious that it isn’t “one side says this the other side says that” - no, an ex military guy said this.
