Point and Spatial Data Questions

Hi:

I have several data sets, including US address information along with services that cover ad hoc regions.

I would like to provide both the ability to query an address, name, range or map area and display the results in a summary and / or map,

or view an organization's service area (ad hoc map via .shp or similar) and display the addresses/services within that area on a map, or summary, or both.

How might you approach this in 2022, and beyond from a data storage/update/management perspective along with interfaces for www and other services?

TIA.
