You don't quite say, but I get the impression you want to keep working as a PM, not a software engineer, but be able to do so in these areas?

I think a masters that gave you expertise in the subject area be better than a generic CS masters. These are quite different areas. For medtech (and possibly BCI) medical compliance qualifications might open more doors than CS. For AI a masters in CS focusing on AI would presumably be a lot of use. I have no idea about aerospace but its seems likely that a different degree would be better than CS.

If instead you want to become a software engineer, then by all means do a CS degree, perhaps one which allows you to focus on the deep tech domain that interests you most.
