Since you mentioned the Ruger Mini 14, you might want to consider the Mini 30. The old stories about inaccuracy are ... old. Fixed now for about 20 years. A little more thump than a .223, say if you wanted to shoot through something to get at something.
^^^This^^^.
M1As are nice, but for us old guys, having to pack one around in the field isn't as fun as just shooting one at the range.
A friend brought along his M1A, Mini-14 and M1Carbine to the range last year. I had my two Mini-30s.
Being able to shoot them side by side for a couple hours made me realize how much I like my pair of Mini-30s.
The M1 carbine, while light and handy, was like shooting a .22 compared to the others. It was pretty minimal out at the 200 yard gong.
The M1A, it had the longer range punch, but was like holding up a lead filled boat paddle, and the extra recoil made follow up shots a bit slower. And his standard model wasn't any more accurate than my Mini-30s when shot for group. Sub 2 MOA.
His Mini-14 was accurate, pretty easy to hit the 200 or 300 yard gong. But the difference in striking energy was apparent.
I had just got one of those paddle targets made of AR500 steel that flips around when you hit it.
The Mini-14 wouldn't flip the target around, it just teetered back a few inches. The 7.62 x 39 and 7.62 x 51 flipped the target around to the next paddle with authority.
To me, the Mini-30 is the just-right blend of power, accuracy, weight, reliability and handling.
Even with just a FastFire red dot, I can smack the 300 yard gong every time from sitting, kneeling or prone, and more often than not from the standing position.
Aside from the obvious self defense usage, the Mini-30 makes a great hunting gun for small to average deer and hogs.
I've shot several Montana whitetails with Hornady SST loads, and in a couple weeks I'm headed to Texas to visit relatives and will try to shoot a hog or two with it.
If you want to use your carbine for hunting, the Mini-30 makes more sense, in many states the .22 caliber Mini-14 isn't legal to use.
Don't believe all the horror stories you hear about the Mini-30 on the internet. Take it from someone who knows them inside and out. If you get one, check out the Mini subsection on perfectunion.com, the best pool of knowledge about the Mini carbines.
Don't waste money on aftermarket magazines, stick with Ruger ones. With good magazines, the Mini is one of the most reliable semi autos out there.
It, like the Garand, M1A and M1 Carbine, keeps all the fouling away from the action, and what fouling that occurs at the gas pipe and gas block will not impede functioning.
Don't buy the worst ammo made for the 7.62 x 39 (Tula) and expect stellar results. Red Army Standard, MFS and Brown Bear are much better, and Silver Bear is better yet.
For just a few dollars more per box than the cheapest Russian stuff ($10 instead of $7) you can get Boxer primed, reloadable, brass case like Geco, Fiocchi or PPU if you shop around.
