For beginners? Fighters tend to be my go-to suggestion, or, if you want to do magic, pick maybe a sorcerer or an oracle. You can pick blasting spells, or ones that alter/obviate the terrain. Or a witch, who can pinch-heal, summon, buff, and have a few fight-ender spells, in addition to hexes you can use round after round.
Or a standard bard. Stand back and make everyone better at everything. You can be the Pathfinder who takes care of all the documentation. If you don't want to sing or dance or play an instrument, make your Performance skill Oration, and just yell at everyone to do better!
I don't recommend classes who come with animals or anything, since that'll require having a second character sheet. Summons work okay if the GM is willing to take care of the monsters for you, or if you just open up the beastiary and know what the monster can do ahead of time.
Though really, ask your GM and the other players for help. If you've already got an idea for characterization, they should figure out how everyone can accomodate each other.
