" If it's not "one-size fits all" doesn't that mean different modes are preferable for different students, wouldn't it be reasonable to call these modes "styles"?"

Not really, because a.) it is often situational b.) you can get better at learning with other "style" if you are exposed to it more c.) it is more of a scale then discreet grouping.

The individualization is not so much about always talking vs always reading. It is more about identifying individual stumbling spot, figuring out what the child missed in prerequisities, whether the child does not develop faster/slower then expectation, adjusting breaks to individual attention span and so on.
