Maybe Lucy finds a long - lost spell book that belonged to a powerful Celestial Mage in the past. The spells in this book are the key to saving everyone. She spends time deciphering the ancient spells and finally manages to use one that can nullify the threat facing Fairy Tail. It could be a spell that can erase the existence of a powerful dark magic or something like that.
Sure. One popular 'david x lucy fanfic' might be 'David and Lucy's Adventure'.

In a battle against a group of powerful enemies, Natsu overexerts himself and is on the verge of being defeated. Lucy steps in. She first summons all of her available Celestial Spirits to create a powerful defensive formation around Natsu.

After that, she uses her healing magic (if she has developed such in the fanfiction) to nurse Natsu back to health.
David was this young lad who was taking care of his father's sheep. He was not from a military background but was chosen by God. In the story against Goliath, he showed remarkable bravery.
