Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
There are definitely spoilers if you haven't read the books yet, but to Varys:
The good of the realm is putting a Targaryen back on the throne. This is evidenced by him killing Kevan Lannister and Grand Maester Pycelle while saying that he was grooming Aegon Targaryen for the throne.
Thus all his plans revolve around this.
