Thanks for the response, I'll give Debarralizer a try. I've also noticed a very significant difference among RAW converters in their ability to remove CA. Surprisingly, I've found that Canon's own RAW conversion tools are the best at removing it, even compared to otherwise superior tools like Adobe Camera RAW and Capure One DSLR (and yes, I've double checked that I have their "moire filter" options enabled when testing them). I like being able to minimize the CA right in the RAW conversion process, since it avoids the extra step of using some other software to remove it, so as painful as it is I've actually gone back to using the Canon RAW conversion utilities. It'd be great if some of these other RAW conversion programs could improve their CA removal algorithms. But since it looks like Debarralizer is a Photoshop plugin, the combination of Adobe Camera RAW and Debarralizer sounds like a good solution, since I can do everything from within Photoshop.
