I agree with many of your statements
But the way you have placed the sabbath commandment with the laws and commandments that were nailed to the cross is wrong.
Sin is the transgression of the law. 1 John 3:7
When Adam sinned a law condemned him. He transgressed a law.
When sin did not exist there was no need for the laws that were added because of transgression. Gal 3:19
There are two laws
The moral law that defines sin and the law that was added to show us how sin was to be delt with. The result and remedy for sin.
One the one that pointed to Jesus was the teacher or shadow which was taken away when Jesus came.
No more blood offerings....
The sabbath is part of the moral law and was not taken away at the death of Jesus...
The deciple and paul kept the sabbath after the death.
And Jesus said....
Mat 5: 17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. 18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. 19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Rom 3:31 Do we then make void the law through faith? God forbid: yea, we establish the law.
Rom 7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.

Keeping the Sabbath is a commandment for the Jews to commemorate God's creation and when He stopped to observe HIs creation in History. It was given to the Jews to follow so that at the time of Jesus Christ keeping the Sabbath would be an issue in condemning Christ.
When Christ died on the cross, the veil to the Holy of Holies was rent. That means that we now have direct access to God our Father. In John 4: 20-24 the Samaritan woman asks Jesus if men ought to worship on that mountain or in Jerusalem. Jesus reply was that the time will come when true worshipers will worship in neither place but will worship in Spirit and in Truth. You can worship together in one place or you can worship at home alone or with family members and friends. Every day is the Lords and should be included in our lives.
That is why Jesus is the Lord of the Sabbath.
