When it comes to concrete, besides metal anchors like lag shield we have the plastic ones being: wall plug, plastic anchor and ribbed anchor. Is there any other (non-metal) anchor that can be used on concrete?
Plastic anchors are by far the most popular. You get them when buying stuff to hang on the wall.
However in my research it seems that wall plugs (below) are better rated (higher weight support).

While wall plugs are not as or even more popular than plastic anchors if they are better rated? I've never received them in products purchased, it has always been plastic anchors.
Personally, it seems to me they would just slip (especially from the ceiling) as they seem to be smooth outside.
I have a project to hang a wood panel to the (concrete) ceiling. I was checking about non-metal anchors because metal anchors wouldn't allow multiple replacements of this panel and also usually requires big holes/damages. I know Tapcon would be the most recommended, but I wouldn't be able to reuse the hole when replacing the panel so it's a no for me. I found these three types listed above, and also read about one with/made of "lead" (if not mistaken).
So, I'm curious as to why one would use plastic anchors when ribbed anchors look to be better, and why use ribbed anchors when wall plugs are rated for heavier stuff.
Like everything, I know there are specific situations. However I could not find when one would not use a wall plug and instead go with a plastic (non-ribbed) anchor.
For hanging stuff on the ceiling, which non-metallic anchor would be the best?
I appreciate any insight on that!

It is risky ,no matter what you use. A concrete floor/road is basically in compression. The bottom of your ceiling is in tension and concrete is generally considered to have no or poor tensile strength. There should be steel rebar in the ceiling , I would verify the presence and amount of rebar before putting holes in the concrete. Each of those anchors works by putting compressive force on the concrete in the concrete ; this compressive ( expansion ) adds to the tensile stress. I would check with local contractors and find out what they do.
