Yubikeys are awesome for ssh...
The problems come from yubico’s multiple apps and different places you have to configure them. On top of that, the gpg agent commands are so verbose and very annoying, especially if you just want to duplicate your key across multiple yubikeys!
Shameless plug, I also wrote an article last year that goes into this, and included setting up commit signing, and even how to duplicate your ssh key across multiple yubikeys.
I also went over how to handle using multiple keys on the same computer since the gpg agent really doesn’t like that for some reason...
