Currently, the Spatial Join tool in ArcGIS Pro contains the Match Option "Have their center in" which calculates a features center (centroid) and uses that to match the target feature. My idea is to add the option to "Have their INSIDE center in", or maybe a conditional check box that appears when the "Have their center in" option is selected that forces an "Inside" calculation.
Currently, a Spatial Join with this Match option selected would return the Default option shown in the graphic below. I then have to add a search distance to get the polygon to select correctly, but this also has risks of selecting the wrong feature should another feature exist close by. Have the option to force "Inside" centroid calculation would ensure we get the match we desire.

This functionality already exists in the "Add Geometry Attributes" GP tool.
