It's been years since I last played it, so I'll probably be way off.

Ignoring strategies that break the game, I guess you should decide in advance what role each character will have (eventually you'll have 4) and build a varied party (e.g. a melee fighter, a defensive mage, an offensive mage, etc.).

As Tar says, you should be OK as long as you do anything that's really out there. Your options are limited for a while anyway as you unlock jobs gradually through the story.

The cool thing is that you can equip an ability from another class as long as you've learned it, so using a class for a bit and then ditching it isn't necessarily a waste.

As for specific classes, I remember the Time Mage being pretty good with its Quick spell, among others. I think Samurai and Ninjas are decent too. Oh, and Summoners.

The Summoner requires that you complete certain quests, so don't miss them. At least that class gives you an added incentive.
