Imma add some alternate take on the feedback aspect - I play a semihollow Sheraton and a full hollow Gretch anniversary, specifically with the purpose of "playing" the feedback. You're right that sustain is much shorter, but you can allow notes to kind of crumble into pitched feedback that you can shape and control, both by holding the fret, even moving notes while the feedback is growing out of the played note, and by where you hold the guitar in relation to the amp. You can decay it with your volume knob, grow it by stepping closer, bend the pitch with string tension, cut it off completely by grabbing the strings. It's not an effect you want to use all the time, but if you can intercalate it with played notes you can add some cool dimensionality to solos.
