Fun classe/build to play

Hi guys,ad title in searching for something fun to play. Im already playing a shield bash based build and i love it. In this party we got a monk,an unarmed strike barbarian(inspired by One punch man) and the marvelous swashbuckler swiiiishhh...oh and a caster(i don't know more about this). It seems that this party needs a ranged class or maybe an healer but i don't want to play an Archer/gunsilnger that got just damage...maybe a cleric... Some hints?
