I have a bachelors degree in computer science and engineering. I can tell you that throughout my 15 years of career as a software engineer (mostly backend, in fintec and JVM languages) the only things that helped me from what I learned in university were algorithms, data structure, cryptography and database internals.

Apart from that, everything else I learned when I started working (aws, design principles and coding conventions, system design patterns, domain driven design, etc.) I had to read so many books after university (pre-AI era) to learn all those things. That's what I would suggest. There are great books to learn algorithms, and data structures which is fundamental.
