The options appears to be an ACH initiated from the Wise side for 0.28% fee, or sending USD to a GBP-denominated Wise account, which I expect would at least incur the sending institution's SWIFT fee.

Your Wise account should give you ABA/account details for a US dollar sub-account, so you can wire USD from your bank to the US "side" of your Wise account. Should cost next to nothing.

You can then do the FX at the destination using Wise, they have rates that are better than most, AFAIK second only to what you get at an Interactive Brokers account. IB plugs you directly into the global forex market, so the spread is essentially unmeasurable. There are commissions, but my last one was 0.0002% of amount converted.

You can generally pick your format from there, I click on the "download PDF" button.

I love my Wise account - I have a cottage in a country other than my home, but I don't need a bank account there because I use the Wise account details for that local currency for pre-authorized debits for all the utility/insurance bills and local spending (card or cash withdrawals). Even for things that require a local bank account, it LOOKS like a local account to them. The only disadvantage is that you have to hold a positive balance at Wise on which you earn no interest.
