(Wife bought me a DeWalt 20v Cordless drill for a Christmas present and I was thinking of getting a matching 20v cordless impact wrench that would be able to use the same batteries, but at $200+I can't see that as being the best way to go given the limited use it would have.)
I don't think you're looking at this the right way. Once you are set on a brand, you'll get batteries with purchases of new tools. As a home owner, you really only need two batteries and one charger. Most decent brands should come with a quick charger, and even going full blast with a tool, the fresh battery should last you long enough for the dead one to charge. Corded tools do have an advantage as far as raw power and staying power, but don't completely write off the cordless stuff. I started out by buying a drill + impact driver set with two batteries and a charger. I often use both at the same time where I make pilot holes with the drill, then sink screws with the impact. It's probably overkill on some of the stuff I'm doing, but certainly not when finishing or working with smaller material. For example, I did that on every fence I've ever built, and having to drag an extension cord all across my yard with a split head and two corded tools would be a major pain.

When I built my chicken coop I was using my impact, drill, sawzall, compound + miter saw, radial saw, a jig saw, and at one point I even brought out the Dremel. That's up to seven power tools, and would have been a lot of cords around. I had enough trouble with the cords of the two big saws and the jig saw. Just something to think about.

I run Ryobi stuff, and while that's probably not a brand anyone was considering I can comment on the battery life. I don't have issues with the batteries not being charged when I need them, with the exception of using a drill or impact several times for small tasks over months, then having batteries die quickly when I start a big project. At the same time, I've got four batteries and two chargers so batteries never slow me down. My batteries are years old and the normal sized battery will get me through about two full sheets of 19/32 subfloor (6' around the perimeter and 8-12" in the field) worth of screws. The big battery about five full sheets worth of screws. It doesn't sound like much when put into that context, but driving 1 5/8" screws continuously, either size battery will last long enough for the other battery to fully charge.

Long story short, you should be able to work yourself to exhaustion and never run out of tool power as long as you have one more battery than tool you are using.
