1 turn 3m humanistic documentary is suitable for 35mm, 50mm or 85mm fixed-focus lens?

If you use a focal length of 50 or 85mm, it is obviously not the whole body, so 1 to 3 meters can only be used with 35mm if it is necessary. Documentary photography is generally about the person and place where the incident happened, so it is generally a big scene shooting. Personally, I think it is too close to expand the shooting distance 1 to 3 meters. Of course, if you want to shoot special effects, that's another matter. Personal advice, limited level.
