How to do this in 2024? I'm using BC 26.0.0 and the console window gives this error that only legacy wallets are supported by this command.

And no indication is given as to how to do it for "newer" or non-legacy wallets. So in addition to backing up wallet.dat, how do I export the private keys?
You can either export the master private key or the descriptors from
listdescriptors true command.
Exporting individual private key isn't safe with the current derivation method used in the new wallet type which doesn't use "
hardened derivation" at address_index.
If you really need the private keys of one of your address, you can manually derive it from the master private key with the derivation path indicated in its parent descriptor using any reputable tool/client.
