Expected User Interaction behaviour for selectable tabs laid vertically

Context
I'm working on a user preferences settings page where a user can choose between products and features for themselves. The "Product Settings" section below is where the user can select a product and configure some of its settings.

Problem

I'm confused about a few things regarding the interaction and user expectations.

  1. What should the default selection be? Should it be something like in the wireframe above with "Choose a product from the left" written? or should it default to the first product's configuration view?

  2. Should clicking on the product name also automatically activate the checkbox? Especially because some products do not have any settings to configure yet and can only be either activated or deactivated. enter image description here

Note:

This layout and interaction is largely inspired by Safari's extension settings workflow. Is this a common design pattern? Is there a general name for such a layout?
