I guess what I really care about is "how much good does my donated dollar do?". Compare a dollar donated to expensive cancer research in the west with a dollar spent on cheap treatments which we already know to work in a developing country. How much of my dollar goes to CEO and staff pay is part of the calculation, but not the only part.
The Effective Altruism movement aims to direct money towards these activities with maximum impact. But to do this they actually need charities to collect data to measure their impact, which I guess may require some degree of professionalism.
