You'll find no shortage of advice telling aspiring cybersecurity professionals to learn how to program—usually in Python. I humbly submit another language may serve you even better:

SQL.

Learning how relational data is queried, aggregated, and presented will translate to any number of processes.

When you learn how the data layer is queried, suddenly what you are presented in the application is no longer magical. You know how to ask for what you want, and how to talk to the developers of tools you use to improve the UX for what you need.

Or to just ignore the application because web apps are slow and sql is fast, and nothing is hidden.
@FritzAdalis Also that!
