Context
With no scenario as a basis, I can't offer a clean "one gun for everything" choice.
Post apocalyptic scenarios, where manufacturing has mostly ceased, will dictate a rather different choice from a context where ammo continues to be easily available.
Assuming availability of ammo -- or at least components -- I'd want something that's as versatile as possible.
I can envision a scenario where I'd take a Ruger 10/22 and a truckload of ammo, but it's a pretty narrow case, so we'll let that be.
I have a fondness for the M1 Carbine, despite its limited range and hitting power. It's a fine choice for social work, can take deer-sized game (larger, if you're good), and won't destroy your rabbit/squirrel/marmot if that's all there is. It's a light rifle and carries easily. The ammo is light and compact, allowing for a substantial on-person carry count.
Having said that, a little more versatility never hurt anything, so . . .
The Marlin 1894C permits a wide range of loads, given that it shoots both .38 special and .357 mag cartridges. A down-loaded .38 will do edible rodents, regular .38 will do varmints and social work, and .357 will do big stuff, all the way up to elk. The .38 & .357 family of ammo is available most everywhere, and reloading for it is way more common than .30 carbine.
You give up capacity and speed, and in return you get more flexibility and better range.
Therefore, in a "one rifle only" world, as much as I would love to go with the carbine, I'd have to pick the 1894C lever gun.
