What is the reality of Al-Baydawi's Tafsir and his biography, and is his Tafsir as reliable as the Tafsirs of Al-Qurtubi and Ibn Kathir, especially since Christians quote him regarding the crucifixion of Christ and other beliefs?

Al-Baydawi is a reputable exegete, and his exegesis does not affirm the false claims of the Christians. Rather, he mentioned what pertains to the crucifixion of the human nature (nasut) among the narrated sayings of those who differed concerning Jesus, peace be upon him, in order to expose their lies when interpreting the verse: "And indeed, those who differ over it are in doubt about it. They have no knowledge of it except the following of assumption. And they did not kill him for certain. Rather, Allah raised him to Himself." And it is not surprising for Christians to have a mistaken understanding, due to their belief in what sound minds do not accept.
