The best credit cards may come with annual fees or require a certain level of income. Most banks have just basic cards, with 0.5 to 1% cashback or rewards.
Interest rates on savings accounts are low although you may get 2-3% with some of the online banks (Alterna Bank, EQ Bank, Simplii, Tangerine). However my advice at the beginning is just to find a large bank that is close to your home to get their newcomer package and get started. Once you are more established and earning income, you will have all the time to look into other alternatives.
