Segmentation
A CA hierarchy enables you to have a level of segmentation between different uses cases for the PKI. This applies both to administration and the role of certificate authority.
Separating administration roles allows different people or functions to manage a certificate authority. Having a segmentation of duty at the CA level reduces the blast radius of a compromised CA and gives flexibility to the parameters of the certificate issued by a CA. For example, this enables different certificate lifetimes issued on certificates per CA.
