> a natural fast typer will naturally lean away from home row "touch typing" to a top-middle row hover style of typing

Yeah, I agree. I've noticed that some folks who reach 160wpm+ start to move off from the standard, "best practice" touch typing technique. With the hand guide visualization on https://www.typequicker.com I focused on just following the common "best practice" approach.

I should add a comment somewhere on the site that these are just the general recommended finger placements and not gospel.

Certain keys are just more comfortable with variation. I use an orth keyboard split keybaord as well so for me especially the Z key makes sense to type with pinky. On a standard qwerty keyboard, I've seen folks do both pinky and ring finger.

I don't think either the correct way - whatever variation of standard touch typing feels better and helps you type faster is the solution
