Having an Apple Watch now for about 6 months, I can say I love it, and none of those things (and I shared the same skepticism before buying one) have proven to be issues.
I don't tend to look at my watch when I sleep - so that one's easy, and when you charge the watch its in a mode that gives off a low-light time (nightstand mode, i think they call it). On top of that, it takes about an hour to charge, so often I end up charging it during my night time regiment, and by the time I go to bed, i COULD wear it (if i need to make sure I'm up early for something, i wear it so i get the vibration)
If you want a traditional watch, then get a traditional watch - comparing it to a traditional watch and holding to the same standards is not a position of common sense...
