Arcade Pop-up: Better option than intersect to pull data from another layer

Hi All,

I'm using an arcade pop-up to pull existing and proposed zoning into a parcel layer. The zones are coming from a separate layer so i am using the "Intersects" arcade function to add this data into the parcels layer.

However I am returning multiple zone values for edge cases. Where a parcel is on the edge (similar to intersect in a select by location) I am getting a zones that do not reflect the correct zones. Any better way to use arcade ?

Use Intersection then iterate through the featureset to return the largest value i.e. the greatest level of overlap.

Example here:

We do this, and have seen this problem as well. Possible solutions:

Use Intersects(points, Centroid($feature)) to grab only the zone that falls under the center of the parcel. Works great unless the parcel has a wonky shape.
Use Intersects(points, Buffer($feature, -5)) to back off from the parcel edge a little.

You could actually do both, too. You can check the truth of Intersects($feature, Centroid($feature)) to see if you have a wonky shape, then use the negative buffer, but default to the centroid method for "normal" parcel shapes.
