My goal is to get a precise angle from a tabletop prize wheel (and do stuff with that data). A link to the exact prize wheel is below.

So far my homework has led me to the idea that a rotational encoder is the right type of device to get that information, but there are so many to choose from and I can’t understand all the subtle differences between them.
Can anyone recommend the best one that:

Can anyone recommend the best one that:
- Outputs more than 8 bits of precision
- Works at the edge of a spinning disc rather than at the axis? (I think it might be tough to get to the axis with that wheel)
- Can output the angle to an Arduino board
- Can be managed by a relative n00b (me)
