You might have read some of these, but hopefully these may help
1) Killing the CAPTCHA for better UX
2) This answer from here:
The typical honeypot CAPTCHA field has a proper label: "If you are a human, do not fill in this field." or some other clear label telling the user what it is.
And, as such, a screen reader should read it just fine.
If you're looking for true usability and accessibility, however, then realize any sort of CAPTCHA is a detriment. It's putting the burden on the site user rather than site owner.
Of course, that's often a tradeoff that has to be done for pragmatic reasons.
3) Some websites just automatically jump to "Forgot your password?" screen after X number of failed attempts. This is a great UX strategy.
