What is there to reconcile? I can see no conflict.
In 1 Corinthians 7:8-9 (from which you quoted an excerpt), Paul is not speaking to married people:
“But I say to the unmarried and to the widows: It is good for them if they remain even as I am; but if they cannot exercise self-control, let them marry. For it is better to marry than to burn.”
Verses 32 and following give an explanation of his point. And verses 26-27 sheds some light on the circumstances of the times:
“I suppose therefore that this is good because of the present distress - that it is good for a man to remain as he is: Are you bound to a wife? Do not seek to be loosed. Are you loosed from a wife? Do not seek a wife.”
So how do you get ‘marriage is a requirement for bishops’? Out of that. It’s not and never has been.
