"Cylinder plays" in NFHS

[CallMeMrRef]

As NFHS does not have the cylinder rule, what is the ruling on a play where a shooter takes normal shooting motion and makes contact to the defender's head? Assume that the elbows were perpendicular and not horizontal. This occurred on a catch and shoot from the corner, not a drive. There did not appear to be much contact on the play, but it doesn't take much contact to catch a defender's eye and draw blood.

I realize there were posts of this nature in 2017 with references to a POE in 2012-2103, but has anything changed?

Is this by rule an intentional foul per se?

Lastly, if a stationary defender straddles offensive leg and offense stands up, dislodging defender, is this a foul on the offensive player?
