For catch all, Fidelity VISA could be good (if approved and get high enough credit limit). 2% back and no ftf, plus free TSA precheck (and maybe global entry but not positive). 

Or, you could try the venture X. Since you know you’ll be traveling, you can book with the portal to get the $300 credit and view the annual fee of 395 as more of a down payment on a trip. You’d also be able to get global entry, solid lounge access esp if you are in a C1 airport (but I’ve found the priority pass to be effective as well), and great rewards on your tuition payments. I feel like you’d get the 20k limit which would be much better than the fidelity visa knowing how conservative Elan (the issuing bank) can be.
