k elaborate... it just seems boring to smite "k now i have extra damage" roll roll roll roll roll roll roll roll roll roll roll while my cleric friend (okay hes my brother really) has all these cool spells he can use. Id multi-class into the cleric but i feel like im stepping on his toes. IDK maybe after level 10 (we're at level ten now) more stuff will happen for me if i stick with paladin.
What are these archtypes you speak of?
At lvl ten I would be worried about having TOO many options!
You have a lot of spellcasting by that lvl. There are a ton of buffs you get to use that complement your cleric's spellcasting.
Here, I'll just list all your "active" abilities
1- Detect Evil
2- Smite Evil
3- Lay on Hands
4- Mercy
5- Channel positive energy
6- Divine Bond (That's a big one)
7- Spellcasting up to lvl 2
Plus any items you might have and base options you can take (melee weapons, ranged weapons, reach weapons, combat maneuvers, intimidate, diplomacy, etc).

Archetypes are a bunch of thematically bound replacements for certain class features of the class. All classes have them. For example, the Divine Defender paladin (focused on protecting allies) archetype replaces your mercies with the Shared Defense special ability, changes your divine bond, etc...
