Did anyone list the creatures that can cause the Frightened / Charmed condition?

[Merudo]

A number of races and classes feature provide advantage to saving throws against been frightened or charmed. Halfling gets advantage against frightened, Elves get advantage against charm, and classes such as the Aberrant Mind get advantage against both.

I wonder how prevalent the frightened and charmed condition are.

Did anyone make a list of creatures capable of inflicting these conditions?

These will include anything immune/resistant to the conditions as well, but it's a start:

Keep in mind that dndbeyond has 1,855 monster entries, so having ~80 to go through cuts away 95% of the ones you don't need to consider.
