Access to Goldman/Marcus services, products, etc. with Apple Card Savings account?

I’m strongly considering getting the Apple Card and using the associated Savings account. I know this account is offered through Goldman/Marcus and I would want access to the financial services and products they offer (insights, personal loans, investment account, etc.) at some point. I’ve been in a situation with online “banks” (aka fintech companies that partner with actual banks to provide checking/cash management accounts and such) where I’m not a member of the bank that’s holding my money. That shut me out from access to financial products and services from that bank. I don’t want to see that happen again, which begs the question: will having this Savings account make me a member of, or at least grant access to, financial products and services at Goldman/Marcus? If not, seems like the best option would be to make a Marcus savings account and connect it to the Apple Card.
