Check out Haydn's "Lord Nelson" mass, specifically the recording by Banchetto Musicale (it's very light and clear). For the antithesis of heavy-handedness, pay attention to movements 2, 4, 5, 7, and 12. But the whole thing is only about 40 minutes and really easy enjoy start to finish, especially since those movements I mentioned are meant to contrast with the slower ones.
Movement 5, while not my favorite, is especially notable for being a canon at the 5th. It's quick, fun, the imitative counterpoint is very easy to hear, and at a minute-forty, hardly overstays its welcome.
Overall though, Western music between Bach's death in 1750 and Beethoven was anything BUT bloated and heavy-handed. Balance, taste, and clarity were highly valued.
