Consider renaming "content" to "narrow" in global layout.

What problem does this address?

When somebody is referring to content-width it's impossible to tell if they mean the toggle that enables the alignment options inside the editor, or if they mean the value they've put into the fild under global styles -> layout.

Using content as a name for both is confusing, especially since "wide" is already referring to a size.

What is your proposed solution?

Change the naming of "content" in the global layout to narrow, or the "dimensions" heading to "content-width" avoid confusion.

Also an inclusion of an option and icon for "narrow" would be really helpful and make it less confusing, so that users know for certain that it's the value under the content field with the narrow icon that gets applied. Including it into the "none" setting is too abstract imo because it requires deeper understanding of how WP handles the layout.

This whole concept needs revisiting. As-is, "content" is the same thing as "none", which is definitely confusing.
