Brand Registry with Multiple Trademarks Question

I inherited the brand registry configuration from somebody else and I’m wondering what the optimal setup us for brands vs. connected trademarks.

We have a company name that is trademarked, and we also have various wordmarks and versions of the trademark for the company name. Those to me seem very clear to link to the brand. (Think of Ford as an example)

Then we have product-specific brands for various product names. (Think Mustang or F-150)

Would the product-related brands be linked, or would each product be its own brand? All have at least an associated trademark.

I have dozens that I need to get listed and just want to make sure I do the enrollment process that makes the most sense for enforcement.
