What focal length lens do you usually use to shoot household products? Do you want to use a wide angle

It depends on what you are taking pictures for. If the requirements are not high, the general lens will do.

If you are indoors, it is better to use a wide-angle head with a large viewing angle, but pay attention to perspective deformation.

If it is not limited by the venue, it is best to use a 50-80mm lens.

In short, nothing is fixed, and any lens can shoot any subject. The key is to learn from each other.
