It sounds like you want a gun for both indoor AND outdoor, AND you don't want a full size rifle. This is a recipe for all-around disappointment.
From what you listed, only the M4 has a chance of cutting it. With an easily changed spring, and maybe a second, longer inner barrel (you can hide in a suppressor) it'll do well outdoors. There's several ICS M4 variants, I'd have to say go with the A1 RIS: full stock is the worst of both worlds, regular A1 limits your battery size... RIS at least you can use the fake AN/PEQ to hold a larger batt (they hold up to 9.6v 1700mah). And you can mount accessories and optics easily.
"Everyone has one" - yeah, so what? Sometimes rare guns are rare for a good reason.
