The HTTP with Azure AD connector is the standard action for application permissions, as it allows for service principal authentication required by Microsoft Graph and SharePoint when no user is present. Conversely, the Office 365 groups send an HTTP request action is a specialized wrapper designed to call Microsoft Graph and Office 365 Management APIs using the delegated permissions of the connection owner. While the generic HTTP action can perform these tasks, it is not considered a "standard action" for these endpoints because it requires manual header configuration and token management. The Send an HTTP request to SharePoint action is the most specific, native method for interacting with SharePoint REST APIs using delegated context.
