Charity navigator is generally a good source.
If they rate highly there I’ll just search up the organization’s controversies and make sure nothing is currently going wrong.
At the end of the day there’s no guarantee regardless so just donate and feel good about it knowing you did your research.

givewell.org does kind of the opposite. It ranks charities by their ‘efficiency’ and offers multiple funds for bundled donation according to their constantly updated ranking.
