I guess you are talking about Dungeons and dragons 5th edition (or 5.5) the newest version.
Because in other versions this is different.
5E: Simple martials:
In 5e unfortunately, all the simple characters are the "martial" characters so people attacking with weapons not spells.
I also get sometimes a bit the feeling that more experienced players try to make new people into thr "tanks"/ frontlane for them to be able to play the more interesting (snd stronger) casters, but being in the front lane is dangerous... Thats why for 5e I would recommend:
Archer Fighter
You are dexterity based, which makes you instantly better with non combat parts (dexterity has better and more) skills ans you are more flexible because you can do range really well, but still are fine in melee.
Fighting style Archery, shortbow as your weapon.
For weapon masteries shortbow, some melee weapon(s) with finesse, and (maybe) longbow.
At level 3 for classes you can pick battlemaster, or also rune rune knight depending on how ok you are at that point with complexity.
Older edition
If you mean D&D general, my fsvorite beginner character still is from 4th edition D&D the elementalist sorcerer. Because many beginners want to play spellcasters and this one is simple.
You can choose your element, you can choose an area spell and get 1 single target spell and are an efficient non squishy caster, which can empower their spells limited number of time.
