How to build an app to filter land parcels by multiple themes

I have been tasked with building an ArcGIS Online app that will let users filter land parcels based on thematic categories that intersect them. For example, show me all land parcels that have a waterfall.

To this end, I plan to run an intersect query for each theme and then save the output as a new layer for users to switch on and off.

However, if users wish to find all land parcels where 2 or more themes are present they would need to run their own intersect query in the browser, which could consume a lot of credits.

Alternatively, I could create a matrix in Excel that users could filter on, but with many themes and over 3,000 land parcels this will be very laborious!

Please can you suggest alternative solutions for me to consider?
