[Citi] Add more options for travel credit cards

Hi everyone. I was wondering if I could get recommendations for a travel credit card. I've just finished my Masters Program and begun working so I'm starting to finally get some income beyond my student life. I currently live with my parents and that allows me to save money by saving much more cost of living. Something I've always been interested in is travel and seeing more of the world. I started becoming interested in credit cards more recently with how they can ease this financial burden of flights and hotels, while I use them for my everyday life. The goal is the ability to experience much more of the world while I'm young. I don't care as much for lounges right now. As from the title I am based in SFO and would like a card recommendation that's good for the airport in general. I don't have much travel experience due to me finishing up schooling so I'm not sure what airlines I would take primarily domestically versus internationally, but UNITED is based in SFO. However, I am more interested in focusing on international trips in the next upcoming years such as Europ, and East Asia. Is the general recommendation to focus on a point ecosystem for good partners, or prioritize sign up bonus's since I'm relatively new with only starter cards? The Chase Sapphire caught my eye due to Chase being a UNITED partner and Capitol Venture having their large sign up bonus. Also I'm not restricted by the chase 5/24 rule as I barely have any cards. However, the credit card I've been with longest is Citi and should I just invest deeper in the points ecosystem with a more premium citi card that multiplies the points to transfer to partners. I have about 30K points saved up in citi currently from my student card. I'm open to further research or different strategies to maximize gain. Or what long term plan for cards I should get to make the most of things.
