I'd very much like to double check that I got the 24 backup phrase right. Is there any way I can verify that I got it right, without purchasing a new Ledger to restore to?

Using the standalone BIP39 (https://github.com/iancoleman/bip39) tool to enter your seed and check that the generated addresses are the one from your Ledger Nano. You should download the bip39-standalone.html file and use it on a offline computer so that you don't need to enter your seed on a PC connected to the Internet with the danger of being compromised.
I created a Linux USB Key for this purpose where I copied th BIP39 tool and booted from this key to check my seed.
