If you have a Sorcerer, Ranger, and Cleric..... how in the world are you low on magic usage? That is literally 2 full casters and a 1/2 caster.

Anyway I agree with Fighter for a new character. No need to mutliclass. The Ritual Caster feat is always a great feat for a Fighter IMO. New players tend to enjoy the Battle Master, but go Champion if they are having trouble learning the rules.
