My take, for what it's worth, on priorities for those attractions that now offer FP/FP+. Original list is courtesy poster
Vertical:
FP+ Attraction List, but has been modified to reflect changes since.
These rankings are based on my experience with all WDW attractions and familiarity with each one's popularity and capacity. These rankings are only meant to be an objective list of which FP+ selections have the potential to
save the most guests the most time under most conditions. They do not reflect my own preferences with regard to "favorites", and do not attempt to reconcile all the different preferences any particular guest may have.
Ranking System:
A - A must-get or risk waits of an hour or more. Using FP+ here will usually
save the most time as compared to the attraction's average standby wait.
B - Take it or leave it. Using FP+ here will usually
save some time as compared to the attraction's average standby wait.
C - Chump. Using FP+ here will usually
save little time as compared to the attraction's average standby wait.

Additional Notes
- FP+ will generally save more time when crowds are heavier. Therefore, it makes the most sense to choose FP+ windows in the afternoon and early evening--when crowds are at their daily peak.
- For the same reason, when park-hopping the best strategy is often to make FP+ selections in the second (or third) park each day. (The FP+ system currently allows selections in a single park only on any one day.)
