When I lived in Singapore, I got an American Express cashback card with 3% cashback on the first $5000 and 1.5% unlimited cashback for everything > $5000. They waived the annual fee and there was no minimum spend.

Another card(the annual fee got waived too) gave me free access to the airport lounge in Dubai, which was great, because I could get a free meal, free drinks, and take a shower during my layover.
