Why this verse cannot be about God's son. It is a reference to God's wisdom, personified here, and throughout the book of Proverbs as a female "she" one is to court and espouse in contrast to Folly the adulteress one is to avoid courting and espousing. The point of the verse is that God espoused His own Wisdom before He created anything and created all things in His Wisdom, just as we read in several other passages of Scripture.
There is likely an allusion to what came to be the ancient Jewish concept of God's Shekinah glory.
Wisdom and Logos are not the same thing. One's Logos is something which is borne out of one's wisdom. One's Logos is something which originates in the depths of one's Wisdom.
In Genesis 1:26 the US and OUR are God and His Wisdom portrayed in a male-female image and man, male and female, were made in that image of God and His Wisdom. And when Eve ate the fruit to gain Wisdom, and she gave to Adam to also eat, we read that God says man has become like ONE OF US knowing good and evil. US and OUR are God and His Wisdom at Gen 1:26.
Christ became the Wisdom of God when he was raised from the dead (1 Corinthians 1:30) and his preaching and teaching in the Holy Spirit were thereby spoken in the Wisdom of God during his earthly ministry (Luke 11:49). As he taught us, his words were not his own but the Father's who sent him.
