Recently, we were escaping from a prison, and we used that hoary old chestnut Find the Path. I'm wondering how y'all would adjudicate the spell in regards to the following obstacles:
1) We had access to several spells (e.g., invisibility, wind walk) that would make our egress easier. Would Find the Path advise us to use them?
2) Certain corridors were heavily guarded and others were not. Would Find the Path steer us toward the empty corridors?
3) One key corridor was guarded with an antimagic field which would REALLY mess up our escape (not least because I was carrying an elephant animal companion polymorphed into a mouse). Would Find the Path tell us how to deactivate the antimagic field?

Two things to consider:
1. The spell only gives information with regard to the recipient.
So if you were the recipient, it's unlikely likely it would take into account how unfortunate the antimagic field would be as far as it being a pain in the ass for your animal companion. Since you can pass through the field yourself without difficulty, it probably wouldn't tell you how to avoid the field. However, you might read into the spell that it will tell you the best route that doesn't impair the functioning of the spell itself, since that would impede your egress.
2. The spell does not take into account the actions of creatures that aren't the recipient.
So no, it wouldn't direct you to unguarded corridors, unless those corridors were shorter. I read the spell as telling you the most direct route, regardless of what's on that route. If there are traps or obstacles, it tells you how to bypass them, but it doesn't decide "well route A is shorter, but there's a hundred traps and a lava field which the recipient will have to bypass by leaping from rock to rock, so let's go with route B, which is longer and safer."
In fact, most of the time it just gives you a sense of the direction of the destination, and only tells you which path to take when there is confusion over which of two paths will lead you there. For example, if the destination is north, and you're in a room with a north door that will eventually end in a dead end and a west door that will eventually turn north to find the destination, you'll get the notion that you should go west, since that's the only way to find the destination. But if you enter a room with only an east door and a west door, and both will get you to the destination, which is north, you won't get a clue, since both ways are "the path" to the destination.
Find The Path would also not advise you to cast spells unless that would specifically defeat an obstacle you will encounter along the way. For example, if there were a wall of force in your way, and you had Disintegrate, it would tell you to use Disintegrate to remove the wall. Otherwise, it would select a better path. If the destination is inside solid stone, it might tell you to use Passwall, or if that's not available to you it might say "and start digging here."
