Well, it won't make a highly poisonous gas when it burns... And it doesn't like to/won't burn in air (read self-extinguishing). A good thing if you have an electrical fire... Also, the Tefzel wire is tough stuff. The insulation won't wear through nearly as fast as the automotive will. You should be using Tefzel coated wire where possible. For the amount of wire in the airplane, the cost difference between using automotive wire and aircraft wire was not worth the effort/risk to "cheap out" for me. You can even get multi-conductor shielded wire for your data applications that comes as aircraft wire. RG-58/U is one possible coax, yes. You'll need to consult the manuals for your radio/XPDR to make sure the impedance required is 50 Ohm (I think most are.) I only mention that because RG-59 is 75 Ohm and looks pretty much the same.
