Sounds like they may possible pay the AF for the Plat if it's your "lounge membership?" Centurion lounges are nice, but not always available. In this aspect, you may be able to pocket the money for the Uber and airline incidental credits, as well as use any other perks.
For some business people, the Plat is worthless for expenditures. My company makes me book all travel directly through their partner portal. That is quite common, especially with larger corporations who can secure volume discounts, and preferential cancellations/other terms.
It sounds like you have your hotel and flight situation already figured out to your liking, what do you feel you are missing? If anything, I'd recommend some more generalized spending cards. I love my CSR. Where there's travel, you probably have a lot of dining expense, as well as other "travel". I'd start racking up those points.
