Depending on the conditions you see, there's really no such thing as an "all season" tire. There's snow tires and not snow tires. Not snow tires are terrible snow tires.
This is probably the most meaningful advice on this thread.
As far as wet traction goes, there are "better" and "worse tires", but a lot of of it is marketing. The two most important things to avoid hydroplaning are:
1) Adjust your speed/following distance to the conditions (sounds like the this won't be an issue)
2) Don't try to save a few bucks by driving tires past a safe/reasonable tread depth. You WILL hydroplane on tires that are bald/have too little tread. Other than that it's not worth sweating if you have safe driving habits.
If you're not going the snow tire route for winter, get a general purpose tire where the economics(cost vs. tread life) make sense.
