Divine Might is a good one for a melee Cleric. Two-Weapon Fighting is good, too, and goes well with Divine Might.
Shield Expert and the other shield feats make sense, too, if you don't want to wade into battle with twin maces.
As for spellcasting offensively, you don't really want metamagic feats until the later part of your first ten levels, and even then, as a Cleric, your offensive abilities aren't great. Reach Spell might be good.
