A fast wide prime is the street photography default because it's wide enough for context but light enough to carry all day.
Sigma 16mm f/1.4 DC DN
A fast APS-C wide prime with pro-level sharpness at a third-party price — wide enough to keep the surrounding scene as much a subject as the person.
Best for: Scene-and-subject shots
Sony E 11mm f/1.8
A fast, compact APS-C wide prime — small enough to be genuinely unobtrusive on a street walk.
Best for: Discreet, wide-context street work
Canon RF 50mm f/1.8 STM
A natural, tighter field of view for isolating a single subject from a busy background, at almost no cost.
Best for: Selective, isolated subjects
