I went for an iterative macro to solve the advanced part.

Been a while since I tried my hand at one of these.  Will need to keep working on the advanced solution.

 

A little sloppy on the Hard solution, but gets the job done.

Here is my beginner solution.  I'm still new to RegEx and originally I didn't know/see that you can tokenize into rows so my answer was extremely inefficient.  After some research i got to a much simpler solution!

Solved the Advanced One!  Wikipedia.  Feels like a big accomplishment to get the right answer the first try!  

Spoiler
Step1 - Determined all possible missing values across where the numbers 1-9 were present to get all valid rows
Step2 - Got all possible combinations of rows 1-3, 4-6, and 7-9 where numbers 1-9 resided in the 'cubes'
Step3 - Of what remained got all possible combinations where the columns contained 1-9.

This involved using append fields tool...and bringing column values into rows for logical testing (1-9).
