I would be inclined to say keep it simple.
Don’t use the basic font, choose something easy to read (maybe varieties for on screen and print) and professional. Use white space well, lay things out nicely and easy to read, proper headings etc.
I wouldn’t go crazy with styling as this will make the data harder to read.
If the data can be charted (and this makes it easier to interpret) then do simple charts. But make sure they are easily read and can’t be misinterpreted.
Don’t turn it into an infographic!
Hope this helps!
