John Frame's "Doctrine of the Christian Life" covers this particular issue, it has multiple chapters on it (3 if I remember correctly). You can take a look at the sample PDF on his website. It has 1 of the three chapters talking about the Sabbath: https://frame-poythress.org/wp-content/uploads/2014/04/John-Frame-Doctrine-of-the-Christian-Life-Excerpt.pdf You might want to check Justo Gonzalez' book "A Brief History of Sunday": https://www.amazon.com/Brief-History-Sunday-Testament-Creation/dp/0802874711 Finally, as someone whose church suffered schism on two separate occasions (the first entirely because of Sabbatarianism, the second, partly because of Sabbatarianism), my only plea to you would simply be: Do not make this a hill to die on. It is so not worth it.
