Well, I'm fond of the fabric covered wire like you can get at RadioDaze or AES. The typical colors are available and it 'fits' visually. 20 gauge is pretty typical in radios of that era. Stranded or solid is somewhat dependent on the application. Flexible speaker leads vs fixed chassis wiring, for instance. Size or style makes no difference in actual operation - mostly preference and convenience.
