The main reason to spend money on Pro Advisor is that you have the rights to Premier Accountant, Enterprise Accountant, and even the QB for Mac, if needed. There is elevated support, of course.
All training I have seen is inadequate; I have a lot of ProAdvisor clients for this reason, and I am not a paying ProAdvisor, either. They don't seem prepared for the End Use of the tools and functions, certainly not the same need their clients have. The support articles are often wrong, and the YouTube videos need to be reviewed in light of what makes sense. Example: I reviewed a lot of Credit Card Charge videos that each had things wrong in them. Nothing substitutes for the time it takes to learn things knowing that QB can be used any number of ways, but knowing how your client uses it or should be using it is the difference between being their Bookkeeper and being a consultant. One huge example is Job Tracking and items; any resource you find that tells you to make a JE is likely an error, and going to make a mess in that data file. JE are not used for Names, the Job Reporting relies on the use of items, and the JE does not provide for using items at all. So right there, I know the author of that article does not "know" QB well enough.
I trust a few resources, such as:
