That probably depends on your definition of weeds then, yours seems quite strict? Almost meaing 'pest' perhaps? Here in Western Europe, especially in previous generations, the term tends to get used for pretty much everything which is bascially just a native wild plant. It's ok if it's short grass or when you can buy it in a store, but otherwise the label is 'weed'. And I'm really not exaggerating here. As such if you want to take photgraphs of plants outdoors those 'weeds' are the targets. Even the most common ones tend to be rather beautiful.
