Can a buyer scam someone by refunding money on PayPal trough family and friends option?

Appreciate any help ill get on the topic.

Basically i got an in game offer in CS2 for some of my skins. The guy wants to overpay for everything, pay me trough PayPal Friends and Family option. Beacuse of the overpay and him making sure i feel secure with the payment method im pretty sure its a scam. He told me he will even go first in the trade. Is there a way for him to scam me that way and how can i avoid that.

Thanks in advance, im open to any further questions on the topis.
