Does the hadith "I and the guarantor of the orphan are like these two in Paradise" include marrying a close orphaned female relative, and does one who marries a close orphaned female relative receive two rewards?

In Sahih al-Bukhari, the Prophet, peace and blessings be upon him, said: "I and the guardian of the orphan will be in Paradise like these two," and the guardian of the orphan is one who takes care of his affairs and interests. So, if one's intention is good, and he abstains from marrying the daughters of the wealthy and marries an orphan from his relatives, seeking closeness to Allah by sponsoring her, we hope that Allah will grant him what he intended of kindness to the orphan and charity to his relatives, based on the words of Allah Almighty: "They ask you, [O Muhammad], what they should spend. Say, 'Whatever good you spend is for parents and relatives and orphans and the needy and the traveler. And whatever good you do - indeed, Allah is Knowing of it.'" And His Almighty saying: "Worship Allah and associate nothing with Him, and be good to parents, and to relatives, and orphans, and the needy." And charity given to a relative counts as two charities: one for charity and one for maintaining kinship ties. Malik ibn Dinar used to say that marrying an orphan has a reward, for she is light in burden and content with little. It should be noted that the majority of scholars do not permit marrying an orphan before puberty, and orphanhood ceases upon reaching puberty.
