Weapon type doesn't matter. Daggers will be more expensive though (because they're better, in my opinion)
Also, "hybrid" is a very non-specific term. Do you want to melee and heal? Melee and cast? Melee and heal and cast?
I assume you mean melee and heal, so this is what I would use:
Weapon: EE dagger, with HM if you can find it
Armor: EE/dex padded robe OR dex/HM robe/padded
Main charm: dex/HM charm
Acc charm: EE heal charm
I'd focus more on finding high melee stats over healing stats, since magicians have high base int to begin with. Also, be warned that all of the high end hybrid gear is incredibly expensive
