Summarize string attributes with the largest area contained within a polygon?

Hi ESRI Community,

I am trying to write string attributes from various polygon layers to a parcel (polygon) dataset.

What is the best way to have the dominant attribute contained within a given parcel written to the parcel dataset? (for example, if there are 3 polygons of different categories that fall inside a parcel, assign the category of the one that takes up the largest % of the parcel).

i.e., if dissolving merged datasets, don’t return first or last text attribute but the one that comprises the majority of that parcel’s area?

This would be automated (ideally using model builder, but could use scripting if necessary) over a large area so manual solutions won’t be feasible.

Apologies if I did not explain that very well, let me know if clarification is needed. Simple or complicated solutions are welcome if they get the job done.

Thank you in advance!
