Jack of all trades is the way to go for Red Mage.

They should be on the front line, slashing gracefully and comboing with a sweet looking sword.

TP for weapon skills and MP for buffing party members and enfeebling enemies. Buff spells should last as long as other buffs like Protect. Enfeebles on the other hand should last a shorter time and have lower cost.

They wear medium/light armor so what will keep them alive for close encounters will be powerful single target buffs that they can cast on themselves.

Red Mage should never be as powerful in casting cures or elemental spells so as not to compete with White Mages and Black Mages. They should be there to enhance the party members effectiveness, not replace members roles.
