Alignment should work (Like most other design software) where there is a Parent/Child hierarchical relationship. Currently only "Align to left, and top" behave this way. Align to Center causes the two objects to meet halfway between their artboard positions. This is has been a major issue for years.

1. Touch Parent object (anchored in artboard position)
2. Holding Shift, Touch Child object
3. Selection alignment task
4. Child moves to parent

In addition, the selection of "Align to Artboard" should be an automatic default state for single or grouped objects. There is no need to have a selection for "Align to Artboard".
