The term "wall cavity" usually refers to the space between studs. Outlet boxes are usually fastened to one side of a stud or the other. Sometimes they are fastened to a crossbar, whether metal or wood, so they can be placed anywhere within the space. There are height limitations in order to count as required outlets but may be placed anywhere you need one. They are called convenience outlets and my friends often hear me say that if one isn't convenient, there aren't enough.
If by "wall cavity" you mean a completely walled off portion of a building with no access, something that sometimes happens in commercial buildings, then no, it is not legal. You must have access to any splices in the circuit, which includes end of the line.
any wall 2' or over
Electrical wall outlet having two plug receptacles.
As close as you want. You must insall an outlet a minium of every 12 feet of wall space. If the wall is smaller that 24" it does not require an outlet.
If the outlet is on an outside wall there is a plastic boot that goesaround the outlet. The purpose of this boot is to keep the vapour barrier intact. The edges of this boot are then taped to the wall vapour barrier to make a complete air seal. The insulation goes behind the outlet boot which allows the wall R value to remain the same as the rest of the wall.

None as drillling a hole is NOT the proper job
A Cavity wall has a cavity or cavities within the wall. Examples are masonry, such as concrete block or brick with two separate wall layers separated by a continuous cavity, or a timber framed wall with a brick veneer separated by a continuous cavity. The cavity is often used as a drainage or ventilation space, reducing moisture transmission through the wall.
The wall of the pulp cavity is surrounded by Dentin

I`m not an electrician but have done some commercial renovations and I believe you should not have holes in a bay on both sides of the wall. if the outlets or switches are on the same side its ok. but check with your electrical inspector.
A dedicated wall outlet is the only one on the circuit.
