I currently use the Venture X as my daily catch-all and absolutely love it. Looking to add a second card for bonus categories. The important categories for me are dining / groceries, airfare, hotels, and other travel.

I have considered the following cards so far. Wondering if I am missing something or if anyone has suggestions / advice:

Savor: Obvious choice but I will earn only 2x on travel.
CSR: 4x on airfare and hotels is very tempting but most of the credits are not useful for me. So trying to decide if the extra points are enough to justify the annual fee.
Strata Premier: Seems like a great choice but I have no experience with Citi so I feel a little apprehensive. Importantly, I can't find a definitive answer to whether or not the Premier transfers to AA.
WF Autograph Journey: I think this is the best option from a pure multiplier perspective. But I am not sure if the points are that valuable. Wondering if I should bet on the transfers partners becoming better in the future.
Amex Green: Almost the same multipliers as the Strata Premier. But it's an Amex so I'm a little worried about usability in Europe.

Struggling hard with this decision so any help would be greatly appreciated!

Edit: I prefer to book flights and hotels directly rather than through a portal.
