Hi kbodiford, welcome to the discussion boards.
Wow, what a question! There is a good reason that there are several thousand fonts to choose from. Choosing a typeface is an artform; choosing which typefaces work well together is also an artform, and a different one from the first! Any professional typographer would probably need to know what the report is about first of all (stock market results, postcolonialist feminist studies, cubist art?), including its intended audience (CEO, school teacher, grandma?), what language it is in (is it in English? does the text contain foreign languages, including mathematical symbols?), plus how long the text is, whether it is for detailed contemplation and reference or just a disposable informational piece, how many pages it needs to be printed on, etc. etc.
If you are unsure about typefaces, I'd recommend that you simply follow the templates that Apple provides. Most are ok.
My tip would be to choose a single typeface, not different ones for title, heading, subheading, subtitle and body. So many different typefaces can look like an exploded carneval on paper (though if the topic of the report is "Practice and Theory Underlying the Use of Explosive Devices in Recreational Urban Spaces", then this might be exactly what you want) :0)
Follow up with some details and maybe we could throw in some suggestions. Or try typophile.com
In the long run, if the people reading the report have no idea about typography and don't really care what the report looks like (or even specifically ask you why it's not set in Times New Roman and Arial), you might not want to waste your time on them.
