Advice for Fighter (BM) Crossbow build

[Aeoulus]

Pact weapon:
"You can use your action to create a pact weapon in your empty hand. You can choose the form that this melee weapon takes each time you create it. You are proficient with it while you wield it. This weapon counts as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage."

No ritual. You make a weapon from nothing.

.

But it has to be a melee weapon then, right?
