“Begotten” does not mean “created” in either Second-Temple Jewish discourse or Nicene theology
Begotten is equivalent to creation in Proverbs 8 where they are used interchangeably - a passage that early Christians used to apply both descriptions “created” and “begets” to God’s creation of the prehuman Jesus in Greek.
22 The Lord created me as the beginning of his ways, for the sake of his works.
23 Before the present age he founded me, in the beginning
24 Before he made the earth and before he made the depths, before he brought forth the springs of the waters,
25 before the mountains were established and before all the hills, he begets me.
