Do not cache variables with a null check in OnValidate unless they are global, as if you copy-paste component values they will not be contextual to your new instance.

Also, if you want to use this to cache variables into serialize fields, I would avoid it. OnValidate is called a lot, and is a likely culprit contributing to editor slow-down.
Instead, use Reset, which is only called when adding or resetting components. Avoid using HideInInspector, just allow users to see the reference and reconfigure if they'd like.
