Is the New Catholic Teaching Against Capital Punishment binding?

Since Pope Francis updated the Catechism of the Catholic Church in 2018, there has been a lot of controversy and debate among Catholics in my area over the issue of capital punishment (unfortunately, rude things were often said on both sides of the spectrum). Are Catholics required now to oppose capital punishment?

Secondly, what are the best biblical, historical, and philosophical arguments for each side of this debate? Avie Maria and God bless.
