First of all, you probably wanna use a "Get Closest Location" instead of "Get Closest Points"; that way you can get locations between points (say inside a polygon) and expect a useful interpolated result instead of the closest vertex specifically.
ICE locations are based on barycentric coordinates and they magically interpolate the values of the nearest triangle's points that the location location is inside of. So say if you have an equidistant triangle with two points at 100% and one at 0%, if you get the location lookup at the perfect center of it, it should return a weight of 50%. Anyway, from the location "Get Closest Location" gives you, plug it to the Source input of a GetData node set to "cls.WeightMapCls.Weight_Map.weights" -- which assumes your cluster is the default name of "WeightMapCls" and your map the default name of "Weight_Map". Change accordingly if not. That should return you the correct weight value.
