By God’d grace and good teaching on things of this nature, I’ve perhaps got some knowledge to pass on regarding this.
1st - We have to basically realize that this is pertaining to personal dealings with people, and should not extend to decisions made by the Civil Magistrate. Romans 13:4 - “But if you do that which is evil, be afraid; for he beareth not the sword in vain.” Now if it were not proper for the magistrate to render punishment (according to God’s Law, not man’s unreasonable innovations), then it would not be said of him “he beareth not the sword in vain.” And what fear would an evildoer have of that executive tribunal if he knew it would instruct the victim to “turn the other cheek.” ? See Exodus 21:23-25
When the Lord chooses to punish the wicked, He has many tools at His hands. The most obvious is the court and executive system which hears and punishes criminals. However, all of His creation can be summoned to execute temporal punishments (ie. Genesis 6:13, Wisdom 5:17-23).
Well, before I go on, I think you’ve sincerely got it, and since that attitude of Christ is not natural for us to have or even desire, we should give the glory to God when He causes us to be concerned with our response to persecution or ridicule.

I Peter 3:8-15
Psalm 34:12
Surely the Scriptures could be multiplied almost endlessly with exhortations and examples of the like. But since you asked, I wanted to give you more Scriptures to meditate upon through the day. They are instructful to me, for as a little of the fragrance of Christ is enough to fill the heart, it is good for the heart and mind to be overcome with the sweet scent of His Word, for it is then less likely to give way to rottonness or be taken away by the wind.
Finally, your second interpretation, about not holding a grudge, I’ve never heard that before. You could perhaps hold more of a grudge if you “got hit more”, but if a person is a “grudge holder” they are probably not the “turn the other cheek” type. But yeah, it’s certainly better to do the non-violent thing than it is to do violence to somebody by holding a grudge.
