I'd rather have them in 1password because I use too many different computers and it is perfect for that and with ssh agent forwarding

Anything pkcs#11 you can proxy. I'm using that on some systems - I have an old notebook with a nitrokey hsm at home. It binds pkcs11-proxy to a local wireguard interface, so I'm registering systems I want to be able to use those keys to that notebooks wireguard. They still need a pin for unlocking a session as well.
