An RPi would be the way to go if you'd want to make a setup for adoption by many users. Getting an RPi as a controller for the entire system is cheap, and you could focus on making software run smoothly on just the RPi.

I wouldn't be surprised if the RPi would be totally fine to also run the data processing.

Probably even the RPi Zero will be totally fine.
