I’m not seeing the difference between creating a new Group (of Accounts) versus creating a new Control Account that contains subsidiary accounts. It seems that either method would achieve the same result of aggregating the subsidiary accounts.
What is the effective difference and why choose one method instead of the other?
The following guides will help you understand the difference:

The simplest explanation is that groups control where accounts are reported on the Summary. Accounts in groups are summed for display purposes only. But the accounts themselves are still displayed.
Control accounts create subsidiary ledgers. Only the control account appears in the Summary.
