Does 1Password / Windows Hello require a TPM chip and/or biometric authentication?

However, in my testing, I was able to still set up a PIN in Windows Hello after disabling the TPM chip, so you should still be able to use that.

Yes, I mentioned that in my start post. However, I doubt it's safer than a password when there's no TPM chip?

I don't see any instructions for setting up a YubiKey for Windows 10/11. I do see them for signing in to a Microsoft account, but I only use a local account (no Microsoft account) at that PC...
