Polygon to raster with weighted average cell assignment?

I was just using the polygon to raster tool and noticed that cell assignment type doesn't include the option to perform a weighted average of overlapping polygons. For example if a layer has a bunch of polygons (circles) where multiple would fall within the same raster cell (say around 10), could the raster value be based on a weighted average of the polygons' value? Is there another way around doing this in ArcGIS Pro?

Ah this took some head scratching but I think the best way is to run Feature to Polygon on your single FC
https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/feature-to-polygon.htm

which will break up the features where they intersect and preserve non intersecting similar to Union.

Next step is a spatial join with a field merge rule of Mean on your value field.

Target = Feature to Polygon output, Join = Original FC,  Match = Intersect, Field Map Merge Rule = Mean

Final step will be to run your Polygon to Raster .
