Is the leadership of one who has memorized little of the Qur’an valid as a preacher for Friday prayer?

The conditions for leading prayers have been previously explained, and the questioner meets these conditions. As for the Friday sermon, it is not a condition for the preacher to be a scholar; rather, the conditions and pillars of the sermon must be fulfilled for it to be valid. And whoever calls to Allah must beware of speaking about what he does not know, and should preach what he knows and remain silent about what he does not know. That is an act of excellence, and his reward is with Allah.
