The simplest flash possible
First step:
The simplest, smallest, and most automatic flash, the better.
For example, RICOH GR II in program mode with the integrated flash.
Experiment with distances

Experimentation is key
You never know what a flash street photo will look like until you shoot it. Thus, just shoot in order to see how the photograph will look like with a flash.
