Are AirPods damaging to your health?
The only question I could find in your entire statement is 


  Should I avoid AirPods take these issues as valid concerns (sic)?


You posted info from sites that indicate it the levels of EMF emitted are both safe and not safe. 

Apple has stated their products meet all applicable safety and health laws (although we all know these standards change over time). 

For every site that I saw that stated it was safe, I found other sites (mostly natural-medicine sites) that said the opposite. 

So to answer your question, it's completely up to you if you want to use them or not. I would say that based on the fact that you're concerned about this enough to do all this research (and still not come away with a definitive answer) that you should stay away from them and find another product that makes you more comfortable.
