I don’t really know of what cards are available in each country, but here in Portugal there are a lot of cards that give 2-5% cashback on everything and have no annual/monthly fees. For no exchange fees, there’s as an example a card with 2% cashback and no fx fees, no cash advance fees, no fees at all beyond interest if you don’t pay your balance in full like with any credit card.
I’d image that no matter the country, you at least have a card that gives you the same 1% as Revolut but everywhere, including Europe and no annual/monthly fees.
As for US credit cards, for something like half of them you don’t need SSN, just ITIN, which isn’t that hard to get and for a some cards if you’re an international student you don’t even need that. You can look at the following link to start with: https://www.creditcards.com/student/
The Deserve Edu just needs you to provide information you’re a student and doesn’t even require a credit history or a security deposit
