The general advice I've read, including from Dietary Guidelines for Americans essentially states "prefer complex carbohydrates to simple carbohydrates." This is generally due to the fact that simple carbohydrates make the consumer feel less full, leading to overeating, have often very low, if any, quantity of fiber, and/or other nutrients, and are high glycemic indexed, which can lead to conditions like diabetes (see here).
So my question is, assuming a healthy individual who engages in 600-800 moderate to high intensity exercise minutes per week (determined by heart rate level), and assuming 400-500 of those minutes are cardiovascular exercises such as running or bicycling, with the remainder strength training, is there any benefit to consuming simple carbohydrates ever? Can or should they be stripped from the diet altogether? Personally, the only time that I've felt them necessary is in emergencies where e.g. after a long (2-3) bout of cardio exercise, I've accidentally mismanaged my complex carbohydrate intake for the day and am feeling symptoms of low or extremely low blood sugar. I've also seen foods such as candy bars and sodas used to treat a diabetic individual in cases of emergency, however that is beside the scope of this question as in this question I am only curious as it relates to healthy, non-diabetic individuals who perform the aforementioned amount of activity level per week.
It seems that in commonly available guidance and literature, there is little to no benefit of simple carbohydrates, but some risk. However, assuming proper portions, there seems to be little to no risk, but benefits of consuming complex carbohydrates. However, no literature that I've read has explicitly stated whether or not completely excluding simple carbohydrates is appropriate for active individuals.
