I think it would depend on the environment where you want to be a trainer. If you are looking for a position at a Community College or commercial IT training company certifications would probably help get your foot in the door. Of course being able to teach would be important to prevent you getting your butt kicked out of the door
If you just want to make training videos and distribute them through Udemy or youtube or something like that... the certification would probably not be valuable.

Is an RHCSA certification necessary for a Linux trainer?
