I found this website with a lot of different charts of joke count/frequency in each MCU movie, and it's very interesting/illuminating:

I tend to like jokes in movies when they are appropriate for the character, and I tend to dislike movies in which the writers tend to dole out jokes to everyone indifferently just for the sake of forcing laughs. As someone who has avoided some of the MCU movies for this reason, I found this data really useful... and it helped me pick out a movie that had a good balance of humor and serious moments.
You can also see that the joke frequency and count seems to increase with the newer movies (in general - there are movies like Black Panther that are deliberately more serious).
I also like that you can see where in time the jokes occur in a movie.
