No canon law is more sort of bureaucratic stuff, what your looking for is moral theology.
There are a couple books on that but the patron of moral Theolgioans is St. Alphonsus Ligouri and his moral theology (considered the summa of moral theology) has been translated recently.
But for more general intro stuff I've heard great things about this

but a good catechism will cover most of it , I reocmmend this
https://sensusfidelium.us/bible-catechesis/the-catechism-explained-fr-francis-spirago/
if you scroll down you'll see overview of all the commandments and stuff
If you want something from St. Alphonsus he also has a useful summary in this book

For actaully sort of practical stuff for what you do, an examination of conscience which is basically a list of sins to ask yourself if you've done is acutally probably the most useful.

This is a fantastic and very in depth book on it, you can find some shorter/less detailed stuff if you google for them.
