A Quarter sidewalk belongs to the city, and to the carriage behind you
A storefront in the French Quarter fronts a narrow public right of way that nobody on your crew controls.
Pedestrians, deliveries, a tour group, a busker and a passing carriage will all be in frame, and none of them will wait for a second take. An exterior shot that depends on a clear sidewalk is a shot that does not exist on those blocks.
Commercial filming on a public right of way inside a historic district is also not something to assume is free. Worth confirming what the city asks for before a crew, a tripod and a light stand turn up rather than after somebody comes over to ask.
The way through is to make the street the subject instead of the obstacle. Foot traffic past a retail door is exactly what an occupier is paying for, so set up across the street, hold one frame, and let the sidewalk fill and empty. A minute of that argues for a retail location better than any description of it.
Interiors then carry the specification work, because the sidewalk will never hold still long enough. The entry, the ceiling height, the rear, the courtyard if there is one, and the service access, which in the Quarter is a real question with a difficult answer.
