School age kids don’t get daylight in winter. We lock them away indoors until a brief, lunch time recess. Then it is back inside until 3pm. They get home just in time for sunset, when they are locked back indoors after dark.
The only daylight they can feasibly get in winter is after school, and standard time deprives them of it.
Dawn-simulating lamps/alarm clocks are more than adequate for meeting early morning circadian needs; there is nothing capable of replacing the utility of evening daylight.
That’s not actually true. Physical activity, exercise affects circadian rhythms as well, and is a far more important consideration.
Again, the “circadian rhythms” factor of morning daylight can be adequately addressed with a simple bedside smart lamp providing consistent “morning light” to wake up to. That little lamp can start your winter day two (or more) hours earlier than your latitude would otherwise allow.
Stadium-style lighting over my local metro park, simulating afternoon daylight, isn’t nearly as feasible an option.
I did my PhD in a field related to this. Morning light is absolutely the most important. Even more so for school age kids.

That’s true for everyone, but note that I’m talking about the morning here.
PM daylight does nothing for your circadian rhythm and melatonin production.
