'AppleISTCA2G1.cer’ that I use now will expire soon. In this case, which should be used as the new intermediate certificate, 'Worldwide Developer Relations - G4’ or ‘AppleISTCA8G1.cer’?

What is a new one after an intermediate certificate expires?
Unless you’re issuing certificates — and presumably you’re not Apple and thus aren’t issuing Apple certificates — you don’t get to choose the intermediate certificate. Rather, Apple issues you a certificate and you must use the intermediate appropriate for that certificate. So you need to look at Issuer section of the certificate that Apple issued you, and use the intermediate that it references.

Thank you for your response. I see that the intermediate certificate is sent by Client, so it is not necessary for me. Understood.
