Wife is stuck with AMEX Blue Cash annual fee since she’s had it since before we married…looking for recommendations to cancel, downgrade, or change to a different card.

As the title states, she had the Blue Cash Preferred from before we got married and is unable to get the fee waived under MLA.

What is the best way to circumvent the annual fee? We were thinking of having her cash out her rewards, cancel it, and then reapply for it (not sure if there is a cool-down period). We are open to going with a different card. I also have a Blue Cash Preferred and typically hit the annual 6% cap on groceries, so we would still like her to have a card that gets a decent return on groceries, but without the annual fee.

We each have our own CSR, AMEX Plat, and NFCU Cash rewards. I also have the Discover It. Any recommendations are greatly appreciated.
