Something I have done (more of a self-awareness drill rather than training per se) is to practice responding to an intruder using the "finger gun" - i.e. no weapon, just a pointed finger.
I start from rooms I typically occupy - bedroom, office, den - and react to potential intruders breaking in from different locations. My main intention is to plan for the best options of cover, concealment, and retreat. Following my personal rule #2 in a gunfight - which is to not get shot, staying behind some form of cover and peeking around corners is a big part of this.
One of the interesting things I have learned from this is that due to the layout of my house, the vast majority of the time I find if I needed to shoot, I would be using my left hand and shooting one handed if I were trying to expose as little of my body as possible. This has changed my range practice focus a lot, so that I shoot "weak hand" a lot more than I used to, as well as one handed with both hands.
I've also recognized where the best defensive points are and where my best retreat paths are, so that I could cover a doorway effectively behind as much cover as possible while being on a land line phone to the police.
The other trick is to practice this same drill at night with all of the lights out in the house. You can assume that an intruder who just came in from outside probably has adjusted to the dark, so turning a light on when you first get up to see what that noise was may put you at a disadvantage.
I like to practice the dark-house drill three ways. With handheld flashlight, with weapon-mounted flashlight or laser (if you have either) using an unloaded gun of course, and with no flashlight at all. For the flashlight drills you tend to need an unloaded or blue plastic gun so you can get used to dealing with a flashlight in one hand and a gun in the other, swapping hands if need be, peeking around corners and pulsing the light as needed to illuminate and hopefully dazzle intruders. I prefer a small bright (100+ lumens) LED flashlight but others may prefer the big D-cell Maglites that double as a club.
As I mentioned earlier, the main value I get from this is for self awareness and to adjust my range time so that I practice the things I need to work on.
