I guess that's sort of true, but before that point, what you learn of their back history, they seemed to be the type of people who just wanted to live their everyday lives, especially Cloud, who seemed to just want to do his job in Soldier and was pushed to be part of the eco-terrorist group (also btw this game was made before "terrorists" were really a thing, so I don't think many players really viewed them as bad guys at all, just people fighting a corrupt system, or maybe Captain Planet planeteers lol. You only really start to get a glimpse of this line of thinking in Crisis Core (which I'm working on but haven't fully completed yet)).
Cloud is the exact opposite of what you're describing. SOLDIER isn't exactly a "normal job" and IIRC you learn pretty early on that Cloud explicitly tried to join to become a hero. It's just that things didnt go so well and he's the cynical loner merc at the start of the game. The trope of "small town hero" gets subverted initially but then the game goes ahead and fulfills it anyways.
I think Cid is the only party member in 7 that legitimately wanted to just do his job and be left the fuck alone.
I'm checking up on it and it looks like you are right, I guess I either missed that part or forgot (I played the game when it originally released). Still, Cloud wanted to do it in the conventional way, by joining Soldier, he was still someone who sort of just wanted to do his job. And yeah Soldier isn't exactly a normal job, but for games like that it still comes pretty close to normal lol. That's one of the problems I also sort of have with FFVII when I said aspects were overrated, there's too much stuff that is more unrealistic then people gave it credit for at the time. Also FFVII Cid is a really good character. ---
