Learn to love people.

Go out and speak to customers - find out what they love and hate about your product. What's within your power to change? What isn't?

Talk to business people and find out what their priorities are. If they have a target for X% customer growth, what would you change about the product to achieve it?

Get a portfolio. Not just a GitHub page of commits - but a deck showing what management decisions you've made, why you made them, how you got people to support you, what impact they had.

Those are just off the top of my head. Best of luck!

Have a framework which you use to make product decisions.

E.g. if you were told to "Improve feature X" - what are the steps you go through to do so (or to balk at doing so)?
