Does one need to repent of any specific or intentional sins to be saved and in a State of Grace?

Most denominations teach the idea that someone must feel guilt or remorse for their sins and must desire not to do them, however some like those teaching Calvinism or Once Saved Always Saved seemed to stop there while other denominations seem to suggest either certain more severe sins like the Catholics or any intentional sin like the Methodists must be repented of, or one is not in a State of Grace and one will go to hell. There is scriptural support in John, Romans and Galatians for both of these view points. I am wondering about an overview of how the different modern as well as the early Church soteriologies would reconcile the more well known grace passages (particularly among Calvinists and those supporting Once Saved Always Saved) with passages that say sinners would not inherit the Kingdom of God such as Romans 1:29-1:31, 1 Corinthians 6:9-6:10, Galatians 5:19-5:21, Ephesians 5:3-5:5, 1 Timothy 1:9-1:10, Revelation 21:8, and Revelation 22:15. I am curious to know about the doctrine of repentance in the apostolic age as well. I have looked at Jerome, Tertullian, and Chrysostom and how they taught some sins needed repenting of for one to be saved. I recognize from Romans to Revelations that there are lists of sins which say that people who commit them do not enter the Kingdom of God. I also know that the first thing Jesus asked the rich man was not whether he had faith in Jesus but did he keep the commandments. On the other hand John repeatedly mentions that those who have faith will be given eternal life. Romans seems to teach salvation by faith alone at least in the majority of its passages and Jesus also told the rich man that with God anything is possible. One iteration of the decalogue in the Old Testament (I believe it is Deuteronomy) teaches that God is merciful to those who love Him for thousands of generations.
