If you don't mind the walking, requesting the croquet lawn will give you a very quiet little garden courtyard with a view of Swan and Dolphin and the river with DHS boats going by - I love those rooms for the peacefulness, and a side perk is there is a back exit door that is right near the end of the Boardwalk - you're actually very close to the Swan and Dolphin boat dock and can just walk over there to pick up boats to Epcot or DHS - or walk around the corner to the Boardwalk without having to go through the whole long hallways and lobby.
Quiet pool is as it sounds - a lot less noisy so also where I tend to request - some of them may also have a longer walk to elevators or lobby but I prefer the walking over the noisier and busier main pool.
If you want to get really specific, the best 1-bedroom rooms in my opinion are the ones at the ends of the wings that stick out on either end of the main and quiet pool. They're right on the river, with nice views of the water and boats, they all have full balconies the width of the villa, and the balconies are larger and more covered so you can stand out there in the rain. They also have side windows in the living room that look out over the river - the only villas that get a window on the side. When I have garden/pool view, I always put in a request for those specific room numbers and have had pretty good luck in getting them. They are the rooms ending in 26 & 27, and 94 & 95 on each floor (so 1026, 2026, 3026, 4026, 5026, etc). The 26 and 94 rooms face the main pool, while the 27 rooms look to the croquet garden and the 95 rooms look to the quiet pool. 27 and 95, 4th or 5th floor, are my favorites.
Here's the view from 4095:
And the view out of the side window which with the balcony gives you a 270-degree view around:
