It’s amazing zero-crossing edits aren’t standard. In the 90s when we used a Sonic Solutions DAW every edit was made at a zero point. You get clicks because you have a step-function where one side of the edit is low energy and the other is higher. The sudden transition manifests as a click. What I do to eliminate this kind of click is extend the audio on both sides of the edit and apply fades to each. It’s a bit of a pain, but that will eliminate zero crossing clicks.
Then there’s Alex4Ds Sound Only transition here.
