Credit Cards for absolute beginners just out of college

Hi everyone I am 23F and will be graduating from college in May and will be starting my first job at a MNC in Bengaluru. As of now (internship period) a significant amount of my spends go on shopping, pg-rent, monthly investments and dining out on weekends (no utility bills as of now). Post my full time job I am also really keen on traveling (mostly outside the country). Please recommend what all credit cards would be suitable for me in order to maximize my rewards. Also make a bunch of UPI payments here and there. thanks in advance for helping a kid out here :)
