I threw my car up on the lift tonight and lightly tapped a few things with a deadblow hammer to see if I could replicate the noise, but I was unable to find a source of any noise. Everything was tight. I've replaced my springs myself, the struts are visually fine with no seepage or wear, strut bearings are fine and tight, nothing is loose. I've tightened everything down.
The only thing I can't really check are the sway bar bushings, which are up under the subframe. Another source could be the sway bar endlinks.
I checked my LCA bushings, and I saw no premature wear or signs of 'no lubrication.'
