What about Splash Mountain? It gets long lines during the day so a good one to hit first. Also, not the first attraction for most. Cons: being wet at the stat of the day and long duration of the ride (it will take up your first 15-20 minutes of the day even if you walk right on).
Buzz is a decent idea if your group loves to re-ride it and is obsessed with getting a better score. The short duration means you will probably get multiple rides in with virtually no wait.
PP is a good RD because the ride duration is so short. You could ride it and hoof it over to Splash with a reasonably short wait at Splash I expect.
Pirates and Jungle Cruise are on the long side in terms of ride duration and are usually available as Day-Of FPs.
