I went ahead and blew a few bucks a while back and bought 600V teflon silver-plated solid copper 18g wire in several colors from a guy in California who sells on ePay.
I wasted money on a box of multi-colored PVC-coated wiring from the global jungle sales site and the melting point of the PVC is so low as to make it nearly useless. I recycled it all.
Teflon doesn't melt, shrink or offgas at normal soldering temps/times and the silver coating conducts heat/electricity really well.
I use 18ga solid for 99% of my wiring, mainly because it stays in place and I only have to stock one ga of wire. I've used 14ga solid for something like the ground from the output tube cathodes on a 300B amp to the star ground point, and 22ga stranded to power the LED on a power switch.

18 gauge for heaters and 20 for everything else is what I've always been told, but I only know enough to be dangerous.
I use both 18 awg stranded and 20 awg solid, in various places.
