In brief: Depends

Depends how big the cavity was, how much tooth structure is left, and how hard your child's bite is.

Since the root canal removes the life of the tooth, this tooth will become more brittle. I definitely recommend a crown

In brief: Almost always

If the cavity did not involve the walls and it was a narrow and deep cavity a crown is not needed, just a filling.
Unfortunately almost always the walls are compromised and if this is the situation a crown must be done otherwise the tooth will crack in the future.

In brief: Root canal therapy

Yes, when it involves tooth #19 or any other tooth that is used during chewing and grinding food.
Tooth #19 is a first molar and has a large chewing surface with 4 cusps. When a root canal is performed, the tooth becomes brittle and prone to fracture. That is the reason a crown is necessary; to protect the cusps and envelop the chewing surface of the tooth from forces that could cause fracture.
