I don't know how for whom, but for me the symbols in a still life or life have a different meaning in contrast to the symbols of a club or other organization. Although these organizations often resort to the use of well-known symbols.

On the other hand, a symbol can be anything that a person gives a certain meaning to))

In a still life, according to my observations, the symbolism lies both in the subject itself, and in the composition, the choice of accompanying objects. Many still lifes were created specifically for symbolism, hidden meanings.
But I could be wrong.
