What is the virtue of Surat Al-Fatihah for the deceased, and which is better in reward for the deceased: reciting Al-Fatihah or supplicating for him?

Al-Fatihah is a great surah, but there is no evidence to specify its recitation for the deceased. The reward for reciting the Qur'an reaches the deceased according to the preponderant opinion, as does supplication by consensus. If one holds the view that the reward for reciting the Qur'an does not reach the deceased, then supplication is better. If one holds the view that it does reach, there is no need to prioritize, and both supplication and dedicating the reward of the Qur'an should be done. If one were to choose only one, supplication is more appropriate due to the scholars' agreement on the到达of its reward.
