I would like to make a wind direction sensor, and I have found this angle sensor with an output of 0-5V, and it looks ideal for this porpuse with some 3D printed parts. What do you think, does it turn easily enough to a little wind can move it?
That's hard to tell without detailed knowledge about materials and more. Try it!
What bearings will be the best calls for specialists, not hobbyists to answer.

As Railroader says, try it. How sensitive it is to the wind direction all depends on your construction ability. Be sure to get the mounting plate, so you don't have to guess at the screw locations.
You also need to protect the device's top bearing from the weather.

One of the best kind of bearings You can use is of the kind used in watches. A needle resting in …….
You want something like this Continuous-rotation potentiometer. $27 from Mouser.
Are you 3D printing this? I may have a few in my basement that we may be able to work out a trade.

One leight weight rotating sensor could be a grey-coded disk read by an optical sensor. The bearings, at Your discression….

No you don't! A continuous rotation pot DOES NOT mean a continuous resistance. I made a wind vane using a continuous rotation pot from a scientific instrument, don't recall what. The two ends of the resistive material are riveted to external terminals and then there is a gap. Sure the whole slider rotates 360 degrees, but hits the ends and the space with infinite resistance.
I completed the build and tried various programming schemes. The best I could come up with was averaging the readings over several seconds, because the wind here is very turbulent. It sort of worked, but not that well. So, it still sets in the shop.

This model does have a 3° gap from min to max. It is linear otherwise.
I think the only way you will get no gap is with a rotary encoder.
