I carry on my 90 acre farm daily so I have tried to figure out the "best punch/accuracy vs weight" equation. Here is what works for me.
If you want to go with a .22 that's not a bad decision. You can shoot the occasional small critter for food, plink along a riverbank, and it would be better than nothing for self defense. My favorite for carrying all day long is the Ruger Bearcat. Most of my experience is with the older brass trigger guard model but the new ones should be fine and they have a hammer disconnect safety unlike the old ones. They have fixed sights so nothing to go wrong there. If you practice and learn to have a good trigger squeeze they can be amazingly accurate. I've killed swimming water mocassins at much greater distances than I really had any business shooting at them. It's too bad the .22 magnum cylinder didn't work out in the new ones but .22 LR can do a lot of things very well and extra ammo takes up little room.
In larger calibers there are some good choices. I haven't had the money or opportunity to buy/shoot some of the newer titanium guns but they sound good. Guns I actually own and carry in similiar situations would be a Glock 19 (9mm), Rossi .44 Special (spurless hammer and fixed sights), and a S&W 640 .357 (concealed hammer, fixed sights). The Glock is the biggest but holds far more ammunition. I usually just carry a full stick and don't bring anything else (especially with the +2 extender on a mag). It is also accurate and has enough stopping power for most uses. I've killed a lot of skunks and groundhogs with mine. The .357 and .44 would be more for just carrying concealed and reserving for self defense. They do that well. Actually both are surprisingly accuate at moderate distances but bullets are so big that carrying more than one reload is just too much.
Around the farm I tend to carry the Glock 19 (or 17) for general utility and any opportunities at a varmint. If I'm going to go plink in a pond or the creek I usually carry the Bearcat. The .357 and .44 are both full time car guns.
