Can I correct a typo in my published paper if it doesn't affect content?
What is the best course of action here?


Don’t do anything. The confusion and irritation caused by having a corrected version linked or mentioned in your CV is much worse than the typo itself.
Readers of your CV might wonder what exactly you corrected, why this did not happen in the journal version, or why you bother that much about a typo (depending on how you present it). While typos in your CV may be subject to enhanced scrutiny and have an increased impact, typos in papers referenced in your CV usually don’t. Other readers are very likely to read the journal version of the article, so besides your CV your correction benefits only a very small audience.

You can also apply a calculation of time wasted and saved similar to the one in this answer of mine:


Supposing that your typo costs the average reader one second.
Suppose it takes you five minutes to fix the typo and upload the fixed version.
Suppose that readers waste no additional time with being confused about the additional version and downloading it.


Even in this very optimistic calculation, three hundred readers have to read your corrected article to make the endeavour worthwhile.
