Well, no wall will stop drug smuggling. People can literally throw things over it. Probably a lot of drones, too. You can't just build a 20 story wall. Any wall could be breached quickly and moved through before authorities could arrive. Vandalism against the entire structure will probably be high, as will constant repairs.
The best defense would be, as the border patrol agencies want, more sensors and fast response teams, not an, at minimum, $15 billion wall. But Trump cut the funds for the Coast Guard, so that isn't looking promising. So caveman logic will blow a lot of time and money, and destroy border community economics.
There is something better than a wall: A fucking lot of desert and hilly terrain. There aren't many places you can cross the border to and immediately hide. This is why the border patrol plays zone defense.
But playing idiot's advocate, it would be two walls, as prisons are designed; one outer, one inner, with the middle operating like a trap. That would be an easy place to put sensors and make response times more reasonable, since you are doubling the time it takes. You can also add impediments in that buffer zone. Height is kinda irrelevant. Construction materials are a matter of cost... that is a long fucking wall. It has to be strong enough to not be cut or driven through, but cheap enough to build and maintain. A mesh would probably work best; a solid wall would just give cover to anyone approaching from the Mexican side. Electricity is out as an option due to the size and remoteness of the wall, unless you also want to build and maintain hundreds of solar farms. I'd probably go with a two-material design, like a mesh along with a gate or lattice, mesh south side so it can't be scaled by hand. Adding the other material would make it harder to cut through; you'd need two different systems.
I'd say look to prisons or military bases, but the scale we're talking about is so much larger that it is pointless to do more than take cues from them, and military bases rely increasingly on sensors anyway.
