I think regarding submission of wives to husbands, it might be best to look at the fairly straight-forward passage in 1 Peter 3. There appears to be no situation unique to a given area, because he addresses churches in various Roman provinces:
1 Peter 1:1 1 Peter, an apostle of Jesus Christ, To the pilgrims of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
He ties it to holy women of the past, taking it beyond the local situation:
1 Peter 3:5 For in this manner, in former times, the holy women who trusted in God also adorned themselves, being submissive to their own husbands,
He references a specific OT passage for support:
1 Peter 3:6 6 as Sarah obeyed Abraham, calling him lord. And you are her children, if you do good and do not fear anything that is frightening.
Genesis 18:12 . 12 Therefore Sarah laughed within herself, saying, “After I have grown old, shall I have pleasure, my lord being old also?” (NKJV)
Peter references similar cautions to men against treating wives poorly, and assures that women are co-heirs of salvation:
1 Peter 3:7 Likewise, husbands, live with your wives in an understanding way, showing honor to the woman as the weaker vessel, since they are heirs with you of the grace of life, so that your prayers may not be hindered.
Moreover, since Peter himself was married, apparently even prior to becoming a disciple, as we see early reference to his mother-in-law, and Paul's statement about him having a believing wife, we have none of the allegations that he is just anti-marriage, anti-woman, anti-wives, etc.
Matthew 8:14 And when Jesus entered Peter’s house, he saw his mother-in-law lying sick with a fever.
1 Corinthians 9:5 5 Do we have no right to take along a believing wife, as do also the other apostles, the brothers of the Lord, and Cephas?
There is continuity between the behavior of holy women of old, and those in the New Testament era, in a variety of locations.
