You're buying your first bass - That's great, let me first say this; You made the right choice.
Now, with that out of the way, here's how it breaks down (in my mind atleast):
4 string vs. 5 string - It comes down to what is comfortable. 5 string adds the convenience of not having to tune down, but it's not necessarily better. I know you asked if you could play any song on a 4 string, and for 99% of music you'll be just fine. Some people find a 5 string more comfortable, myself included. However, tons of experienced guys play and have played 4 strings for their entire careers.
Active vs. Passive - Active is not necessarily better, a lot of guys prefer the passive tone. Since you're just starting out, and I don't mean this is any offensive way, but you really won't notice that much difference in tone. You just haven't developed the ear for it. But on the other hand, depending on what you play, an Active does give the benefit of boosting and cutting certain frequencies. On the other hand, if you do prefer the passive tone, a lot of active basses cannot cut right out and lose some of the passive tone. Plus, Active Electronics require a battery, not a big deal, but sometimes a hassle when you're in a jam (literally).
Squier vs. Squire (??) - The VM Jazz has a good reputation on these boards, so does the Active 5, but they're basically opposite ends of the spectrum. I think if you're just starting out, a VM Jazz should fit your needs just fine. But again, it comes down to choice and whether you think you need 5 strings/Active eq etc.
Basically, while we can tell you what to do until we're blue in the face, it boils down to what you like because you're the one spending your money for your benefit, not ours. Try them out, see what feels right, what doesn't, and then make your decision.
