[MCU] [Dr. Strange 2 spoilers] Why can't Wanda...

It seems like the ability to instantly deform/destroy some part of a person's body is a potent skill. Wanda uses it to disable Black Bolt (which then kills him), but it seems like it could be used on anyone who opposes her. Is there some reason she didn't use it on Dr. Strange, for instance?

>Mr. Incredible: Wanda, this is Dr. Strange, the person who's been trying to stop you for the past 90 minutes. He may yet succeed due to the fact that his heart is beating, his lungs are able to pump oxygen into his blood and he is not in a state of brain death.  
>  
>Wanda: What heart, lungs, blood and/or brain?

If the answer is, he can defend himself magically, or she didn't actually want to kill him due to their history, is there some reason she couldn't or didn't want to do it Captain Carter or Captain Marvel and chose instead to have a lengthy fight with each?

I took it as arrogance, possibly Darkhold induced.

Wanda humiliated each of them when fighting them. 

Black Bolt; she took away his greatest weapons and let him kill himself with his own power.

Cpt Carter and Cpt Marvel are brawlers, they win fights through pure power and fighting prowess, so Wanda just beat them down with overwhelming force.

Professor X is a master manipulator, literally the master of mind games. Wanda let him in to her mind and then destroyed him psychically. 

Mr Fantastic is stretchy and incredibly intelligent, so she just pulled him apart like a cheese string before he had any further opportunity to strategise.
