Summoning can go well with any of the magic classes. It doesn't rely on INT, but having buffs and debuffs available to you to aid your summons will come in handy. Keep in mind you can only have 1 summon at a time, so only ever equip 2 summon spells, 3 max (excluding totems.) The rest of your skills can involve buffing your party. So you can add a little into Hydro, Pyro, Aero, etc just to be able to buff.
Remember whatever type of tile you summon your Incarnate on he becomes an elemental Incarnate of that type. (For example summoning him on Water gives him Restoration ability and water dmg)
Far as STR and Finesse goes just add a little to them when necessary to equip armor you want to wear (For example sometimes you'll find armor with +2 summoning but it requires 12 or 13 Str/Finesse.) Memory will be your main stat so you can have a ton of choices available to buff/heal your party and debuff the enemy. Wits and INT can be added to for the init bonus and INT will increase magic dmg a bit.
You can always respec for free, any of your characters, once you leave Fort Joy's island.
