There are two different things here that pull me in two opposite directions. First is the marksmanship. For this the three rifles you listed do great, some do certain things better than the others, but all are good options.
The second point is home defense, or at least practice for home defense. In a home defense situation I would not be looking for a bolt action rifle. I would want something semi-automatic, be it pistol, shotgun, or rifle. I think for the home defense idea something on the lines of a Marlin model 60, a Ruger 10-22, or a Remington 597 would fit well. These rifles will teach you basics of how to shoot but will also be usable in more speed oriented drills to practice for home defense. You don't need to be able to shoot bugholes at 100 yards in a home defense situation. You need speed and maneuverability. Something that is fairly compact and shoots follow up shots quickly is my pick, which doesn't fit the three models you selected in the slightest.
So is this to learn how to shoot accurately or how to shoot to survive? That plays all the difference.
I really like the CZ models. The iron sight options are great and the stocks fit very well for irons use. Their sightless models are also designed well and all are of great quality for the price. I also am in love with my Savage Mk II FVT. This gives me aperture sights on a very accurate rifle. It has become one of my favorite rifles to use, though I have been bitten a bit by the prone shooting bug so it take it for what it is. The Kimber is big, heavy, and expensive. I have heard some people claim the accuracy is great while others find it average at best. I have also heard, though have no proof, that the reason the kimber rifles are available is that the government ended their contract with Kimber as they did not measure up to the accuracy guarantees Kimber promised. True or not I can't say. Just what I heard. For the price I am hard pressed to find out first hand. A heavy barreled Anschutz or two aren't too far from the $600 price of the Kimber. These are all rifles to really learn how to shoot accurately, not so much for home defense.
Maybe I misunderstood what was meant but I would be looking at two different rifles to learn marksmanship and home defense.
