This is not limited to just Hawaii, Puerto Rico, Guam, or the Philippines as well as American intervention in Latin America, but it is an important part of it. The question is posed from the time period of 1890-1930 about.
As far as Hawaii and Guam go; none. In each case the population who became US Subjects and then Nationals (not citizens until well after the time period you've set) would have preferred not to be under US jurisdiction. In both of those cases people lost previously held rights and control they would have preferred to hold onto.
Perhaps, though, benefits needs to be defined more clearly if their is something more specific you are curious about.
