Carthage is good as you gain from avoiding wars, so you need some but they are localised and mostly very early in the game.
Dacia is good if you are prepared to wait, but you are very isolated. Once you have built up its a potentially very powerful faction.
Egypt is not bad, in the main the other major powers will leave you alone
India only has one border, but to gain much you do need to engage in a lot of wars
Saba is good if very isolated
For a balanced but not too military game, go for Egypt would be my advice
