Deacon's have to have faculties to preach. Most diocese, if not all, a newer deacon does not have preaching facutlies. They have to have additional classes and formation. If they have preached at a Sunday mass, then they have the faculties.
My church let me know that the deacons typically officiate when it's the wedding without the full mass (no communion), and one of their priests would officiate should we decide to go with the full mass.

The bride's uncle was a deacon of the church and he performed the wedding ceremony.
The pastor of the church was really unknow to the couplte but he did the mass and we had two other priest friends on the altarl
We had both a priest and a deacon present for our wedding. We had the Nuptial Mass.
