Yeah, I think the thing with the more exotic filaments is that it's a more specialized used case for when you still need to retain the lightness of plastic. With something like this, the weight doesn't really matter and you want the big increase in strength or durability that you get with metal. Otherwise I find that correct design in your parts provides enough strength in most 3D printed parts to just use PLA or PETG. Nylon is quite a bit stronger but not worth the effort to try and print.
The carbon fibre nylon is worse than the plain nylon in terms of strength. Which makes sense to me. If you grind up carbon and put that into your filament why would that make it stronger? Maybe for compression forces?
I also think the carbon filaments are BS. I've seen several tests like this one: https://www.matterhackers.com/news/filament-strength-testing
