Morning seems pretty common for stand-ups. Personally, I try to do my heavy cognitive tasks in the morning (so not a fan). I think that some managers use morning meetings as a way to make sure people come in to work on the managers schedule.

Mornings are my “thinking” time.

The good idea/solution comes to me in the shower or while I’m sleeping and I drive to work thinking about it. I’m usually able to get a good start on implementing it before people can interrupt me.

My experience is that start-of-day meeting only works for a team of morning people or they all have kids. People show up at work at different times, and their day start at different times.

Erring on the side of people who have kids is something I gladly do. I do not have kids but if occassionally I need to attend a 10am meeting, that's fair. I can go back to sleep after if I need to.
