Best personal loan for debt consolidation for beginners?

I've been drowning in multiple debts for a while now, credit card balances, a small medical bill, and a leftover installment loan. I'm tired of tracking different due dates and paying way too much in interest every month. A friend mentioned consolidating everything into one personal loan but I honestly have no idea where to start since I've never done this before. My credit score is decent but not perfect, somewhere in the low 700s, so I'm not sure what rates I'd even qualify for. I don't want to get scammed or end up in a worse situation than I'm already in.

For those who've actually done this, what worked for you and what should a complete beginner watch out for before applying?
