What spending/payment habits are best to establish credit with a credit card?

I’m hopelessly clueless when it comes to credit. I have my first card, and I’m finding conflicting things on the internet regarding how to best build credit. I’ve read that paying your balance in full each month doesn’t build credit, because you’re not managing your account, but are just using it as a substitute ATM card.

What kind of spending and payment can help me to best build my credit?

Thanks, ladies and bros. :)
