I used to donate blood, but sadly a medication I take prevents me from doing so anymore. One time I even donated two units since they were particularly low on that type. You have my respect.
I also help do compatibility testing for an emulator, though life has kept me from doing that recently.

That’s the other thing, too. It’s rare to be in a situation where you could inhale it. The only example I can think, which is also a rare situation, is if a vehicle that uses it is involved in some kind of accident and breaks the piece of carbon fiber. That could release it into the air causing you to breathe it in.

If you want a more literal, chemist answer: carbon fiber. Carbon fiber’s chemical structure is surprisingly similar to Asbestos. Even though we barely use it for anything due to the difficulty in producing it, it’s most likely just as harmful to us as asbestos.

This may be out of your price range, but I’ve been very satisfied with my Logitech G915. It’s a wireless, backlit, low profile (so no wrist rest necessary), mechanical keyboard with some programmable buttons on the left side. You can also adjust how bright the back light is.
I’ve been using it for around 5 years now and have little to complain about it. There are also three different switch choices so if you don’t like the clicky sound, you can pick one of the others. I went with linear.
Again, I know it’s pricey (it was $250 when I bought it), but I have had no need nor desire to look for another keyboard since.
