The brand new 220nF cap measured 30Ω ESR on the cheap LCR

That is definitely not right. Film caps are generally very low ESR. I suppose there could be something about the way the cheap tester does the ESR measurement that isn't good for filim caps, or it's possible that it has a narrower range for ESR.
Also possible that it's just not super reliable. I generally use my cheap tester as go/no-go tester and I don't rely on it for precision.
If you decide to get something that is specifically more reliable for ESR, people seem to like
the PEAK devices.
I decided to get
a DE-5000 LCR meter after watching a bunch of reviews, and I'm happy with it. It is not quite as convenient to use as the PEAK meter, but it's got a wider range of functions and seems to be pretty accurate according to the hobbyist community.
