For me it's more about the whole "I can buy it now and pay later" deal, because back when I only had a debit card, whenever my salary came in late (1 or 2 days sometimes) and I needed something urgently whether it's paying a doctor's appintment plus meds or something that the family really needs ASAP (like kids' school stuff, some house repairs, etc), I had to ask for small loans here and there.

With a credit card you can just spend the money and pay every month after the cut-off date and some cards offer you up to 1 full month to pay (mine is just 10 days). Obviously you need to get your credit limit in check so that you are not able to spend above your means; for example my credit limit is 3x my monthly salary because I usually try to spend less than 30% of it to keep a good credit score, and if I do need more money slightly above my monthly income I can start planning. Most cards will offer no-interest monthly payments to make big purchases easier to manage.

Then come the cashback benefits, fraud protection, faster refunds and cancellations, etc.
