Your capsule is gorgeous! My immediate thought is that two swimsuits might not be enough for a week at the beach and poolside. I just came back from a casual visit to my parents in Florida - I thought I was overpacking with four swimsuits - most of which mixed and matched - but in a week, I wore all of them, plus my lapsuit and a rashguard suit. I wore some pieces multiple times.
I think a two-piece that mixes and matches with your blue Esprit two-piece could give you a lot of mileage.
I would also plan to pack (or buy while there) an extra pair of sandals and a cover-up option that you don't mind getting sandy, salt-watered, and sunscreened up. I always somehow think I'm going to keep my shoes somewhat clean, and my coverup pretty out there on the sand, and the beach is always like, 'haha, nope'.
I think a basic white linen button-down, and a basic cotton tank top would serve you well.
I wish you a wonderful trip!
p.s.- While I'm thinking about it, this sunscreen mineral powder by Hawaiian Tropic has become a summer staple this year. I sunburn fast - usually within 12-15 minutes, but I went hiking out on Payne's Prairie a few weeks ago, and forgot to bring a hat. My scalp sunburned, but my face did not, despite it only being 30SPF. My eyes don't usually do well with sunscreens anywhere on my face, but I had no issues with sensitivity.
