If you can still find one, the Arsenal AK's are pretty good guns. For that matter, if you can still find other types of AK's most of them are also pretty good guns. All AK's can accept 5/10, 20, and 30 round magazines. I like the Chinese steel magazines but European steel and Bulgarian steel-reinforced polymer are just as good. There are 5 round magazines for states with hunting capacity restrictions or legislated magazine capacity restrictions. If you live in a state where you can legally own a suppressor, I assume that doesn't apply to you. By 7.62, I assume you mean 7.62 NATO.
I have friends and relatives who routinely use AK's and SKS's to hunt pigs and deer with. You can add a muzzle device from AAC or SureFire to an Arsenal AK to suppress it. The suppressor will cost as much or more than the gun, but that's certainly an option. I like CHF barrels like the ones that Arsenal uses, but mostly I like the fact that the overall machining quality on all the components that have to line up for the gun to function properly and be accurate have been lined up properly (barrel, gas block, and trunnions). I have looked at various different AK's and lots of them have canted FSB's, to include Arsenals. Arsenals have side rails on them so you can mount a red dot optic over the receiver. If not, the Ultimak is your friend.
If you have the right kinds of bullets, by which I mean the really expensive frangible kind, you could plausibly use an AK for home defense. If I could only afford one rifle and needed to hunt with it and use it to dissuade criminals from busting my door down to take what I have, I would purchase an AK if I lived in a free state and a SKS if I lived in a nanny state.
If it were me, I'd factor in the cost of magazines and ammunition if you're going to use it for the purposes you stated.
I only own three AK's now, a Polytech Legend, a NORINCO MAK-90, and an Arsenal SLR-101. I had a NORINCO 84S in years past. All have been great guns. I've shot various different AK's from friends and acquaintances. I wouldn't say that one's necessarily better than the next. You have to configure it for how you want to use it.
Hope that helps
