my theory on the attributes of the 3 variants of pony are

Pegasus: they have a passive magic that is divided into three parts: Aero, a magic which gives them the qualities which allows them to fly (sticking wings on anything doesn't immediately give them the ablility to fly after all), Cloudwalking (self explainitory), and lift magic which lightens themselves and certain things enough to allow for lift off (i suspect Scootloo has a dysfunctional lift magic, which prevents her from flying)

Earth Ponies are stronger mainly due to lifestyle choices. A lot work in labor entensive fields but maybe because of that they might be able to build more muscle fiber faster (adaptation/evolution). as for why they grow the food, i think that unicorn/pegasus magic interferes with plant growth mainly.

unicorns could be more frail due to their reliance on magic. they don't need to be strong but they do need to flex their magic to strengthen it
