Best TD Visa to pair with Amex Cobalt?

I have access to a promotion that allows me to get one of the TD Infinite visa’s at no annual charge.

Currently, I use my Amex Cobalt everywhere I can, and in other scenarios I have the basic TD Rewards Visa. This new card will replace that TD visa.

Which of the following cards pairs best with Amex Cobalt?

TD Aeroplan Visa Infinite

TD First Class Travel Visa Infinite

TD Cash Back Visa Infinite

I am only 23 and try to travel 2-3 times per year as some background.

Please let me know your thoughts. Thank you!
