In this regard a Sorcerer and a Wizard can overlap... because there's no reason why a Wizard's "school" needs to be tied to the eight spell schools. A "school of air control" or a "school of arcane order" are just as viable as the "school of illusion" or "school of transmutation", which makes them functionally identical to a Storm Sorcerer or Clockwork Sorcerer.
Level Up has a number of lesser schools of magic where you could, for instance, be an Air Wizard by simply collecting a number of spells belonging to the Air 'school' of magic.
Lesser Schools of Magic: acid, affliction, air, arcane, attack, beasts, chaos, cold, communication, compulsion, divine, earth, enhancement, evil, fear, fire, force, good, healing, knowledge, law, lightning, movement, nature, necrotic, negation, obscurement, planar, plants, poison, prismatic, protection, psychic, radiant, scrying, senses, shadow, shapechanging, sound, storm, summoning, technological, telepathy, teleportation, terrain, thunder, time, transformation, unarmed, undead, utility, water, weaponry, weather.
