Today I played around with sample projects: Lyria and Matrix. I wanted to see how professional game devs structure their code/blueprints. And oh boy I've seen so many nodes I can't wrap my head around. It took a lot of time for me to understand a function with 30 nodes, which would take me a minute if it was code.

Anyway, I learned that configuring Blueprints is done by Data Assets, where you can put many properties of different type. It's just like a cpp struct.
