Dogs would likely not constitue a booby trap. There are however municipal ordinances and state statutes that few deal with dogs that have vicious or dangerous propensities
Some notable commissions are the Ruger 22/45 Lite, SR9 and P series pistols (unfortunately discontinued), American, and S&W M&P.
I would also suggest that a .22 lever, bolt, or pump action rifle would be more reliable than a semi auto.
However, guns are like women. You like them cause you like them, and I didn’t ask you for your opinion.
Depends: are you a woman or man. If a man, it can ride high and close, with an untucked shirt over it, is one way. Maybe a full size weapon is not for you, or, maybe a midsize.
If a woman, I understand that the are bra holsters. either sex might consider a belly band.
Need to consider reliability, availability of parts and ammo, and use. Also depends on what you mean by “preparedness”. If it means prepping for anything and everything, not sure there are just 3. To decide which firearms, it would be helpful to know how many likely in your group. More people would expand your options somewhat.
To me the starter is a reliable .22 rifle. I have several 10/22s. If just one .22 rifle it would probably be a Marlin lever action or Remington pump. Can shoot short, long or long rifle, and not near as finnicky as a semi auto.
An AR in 5.56 is a close to medium range weapon. Readily available parts and ammo. Also shoots .223 rem but not other way.
3rd choice to me is sort of a very personal choice. I’d probably go with a reliable 9mm handgun. Sig, Ruger, Walther, Glock, are just a few. Go to local gun store and see what is comfortable to you. Try to rent a similar model at a range and see how it shoots for you. Make selection accordingly. I am told that there is a saying that a handgun is used to fight your way to your rifle. Also takes more practice to become proficient.

Good article. I’m glad you pointed out that most exhibitors at gun shows, at least all from which I have purchased, had FFL. I have found that to be 100% when it comes firearms.
Great article. Also try cotton makeup remover circles. I put petroleum jelly on one side. Open it up and the sparks from a ferro rod will light the interior cotton and will ignite the petroleum jelly for a longer burn.
As far as a rust inhibitor is concerned, I use either food grade mineral oil or food grade silicone. Particularly if you are going to use the knife on food. Kydex is probably best to store in as it does not attract moisture like cardboard.
