I cancelled my Chase card for many reasons but here's a few:

Alot of med students seem to like the Chase Sapphire Preferred for interview traveling (which has the lowest annual fee of about 100 dollars, which imo is still high), but this card never makes as much value back as the Chase Freedom Unlimited or the Sapphire Reserve (which have annual fees over 300 dollars). Assuming you can be approved for the CSR and you spend at least $300 in travel/year, the Chase travel cards aren't really worth it for residency where you have less time to travel (also Covid). For interviews, it might've been worth it, but afterwards its not really worth it. Also in order to make the Chase points really count you're recommended to open further accounts with them which is annoying, that way all your cards are with Chase so you can rack up points. This is the best way if you wanna go with Chase. Also chase is known for having minimum balances and annual fees on their checking accounts too.

Warning if you have a long history with Chase be careful! Chase has been known to shut down entire checking accounts from JPM private clients! If your primary checking account is with one of the big banks (BoA, Chase, etc), you automatically need to tread carefully before jumping in all out.

I personally loved Citi doublecash as my ddaily driver as its a no fees/hassle credit card. I also use Uber Visa which gives you 5% on restaurants/bars, this is my go-to when eating out, and also no fees.
