To be honest I haven't used that version yet but you should be able to leave the captcha types as you could in X3, for a very long time now NHSEO has sent the captcha types to CS along with the captcha so it knows which captcha type to use for solving. If the test comes back successful then you should be setup and ready to go.
No because NHSEO sends the type that is currently needed to be solved. I could probably find out but it shouldn't be necessary to check any specific captcha types as NHSEO will tell it when it sends the captcha what type of captcha it is so CS should be using the correct algorithm to solve it.
