So the interesting question is to what extent the Iranian derived Hezbollah "garage rockets" (very poor guidance, CEP is basically "somewhere in Israel", but extremely cheap and require only smugglable parts) can be combined by some power with Ukrainian style precision guidance.

True, though (so far) range, velocity, and payload are far smaller than what we expect for a "cruise missile".

Well, this week proves that range and velocity limitation can be overcome if you ship them near to their destination in small boxes ahead of time. This wasn't really an option with cruise missiles.
