Home defense to me is destroying an intruder that is inside or trying to get inside my home. The only reason I want to take a second shot is if I miss with the first one. I live in a very populated neighborhood in San Jose Ca. I have neighbors all around and think about over penetration.
Overpenetration is something that a lot of people get entirely too worked up about.
Your Fiocchi will do just fine as long as it patterns well. With buck, you need to worry about how much of your pattern will be on the target and how much may be sailing on by. In CA, you may be more restricted in being able to justify shooting someone outdoors, so that may not be a factor for you. For others, an HD shooting could very well happen outdoors. Even inside, having a pattern with leakers going past your intended target can be very bad.
Your slugs are probably not a real good idea except in limited circumstances if you are concerned about overpenetration. Slugs actually are something to be concerned with as they tend to penetrate two or three times the distance buck will, and the retain a metric buttload of mass and thus momentum.

I've seen some compelling evidence (ballistic gel) that 4 buck is much more damaging to people than 00. I don't like posting hot links because I can't remember which boards let you and which don't, but just put "WWW." in front of shotgunworld.com/bbs/viewtopic.php?f=7&t=109958 and you'll get a ton of info. In fact, if you don't want to read a lot don't bother. But if you want to see the damage birdshot up to slugs do on ballistic gel, check it out. I was surprised by a lot of the info.
That depends on how you define more damaging. 4B is a marginal load as far as reliably reaching the FBI standard consistently. 1B is generally the smallest buck that will do that, and there are a large number of projos to do it as well. So in terms of wound tracks, 4B and 1B will provide more of that than 00. However, 4B does not have enough mass to push through deeply enough while 1B typically does and there is really no problem as far as 00. The other side of the number of projos is that you have more of them to account for.
Two things stop aggression quickly without relying on voluntary compliance on the part of the attacker: exsanguination and CNS hits. In order to do either of those you have to be able to get through a lot of body structures, and often they are protected by heavy bone. Even if you have a lot of wound tracks, if they do not reach large vessels it can take a long time for hypovolemia to set in, and that means time that the goblin can continue to fight, even if he is literally on his ass.
The important thing to remember with buck shot is patterning and penetration. Fortunately, the same thing that helps one also helps the other. Plated, buffered shot resists deformation in setback upon firing and also as the shot load rattles down the barrel and gets constricted by the bore/choke. Less defomation leads to better patterns, meaning that you have a fairly tight, even pattern. Finally in terms of terminal ballistics the more spherical the shot the better it will be in penetrating. I am using general terms as spheroids do not have good aerodynamics or penetrating capability (they are in effect the same thing, just different media). However once the spheres become deformed they have increased drag, which reduces their ability to penetrate.
So typically buckshot that is hardened, plated, and buffered will do better than that which isn't. If you add in something like the TAP or FliteControl wad cups you get patterns that are even tighter.
The Hornady TAP and Fed FC loads are going to be the tightest loads you will find most likely. Fed is supposed to be producing a 1B FC load, which will dominate if they actually do it. It will combine enough mass to penetrate deeply and enough projos to allow for a lot of wound tracks while keeping them together well enough to hit hard in a very small area.
