Safety and durability are important for homes with children. A driveway basketball hoop should probably be mounted above a dent-resistant 24-gauge steel door. Ironically, a lower number steel gauge means the metal is stronger. 25-gauge steel is thinner than 24-gauge steel.
Also, look for a garage door with pinch-resistant sectional design so little fingers won't be caught between slats as the door rolls shut. Replace any garage door opener that predates 1992. It may not have modern sensors that stop the door when an object gets in the way.
