Jesus restates the command (Mk 12:30) given in the Old Testament (Deut 6:4) that you shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength (e.g. resources), and you shall love your neighbor as yourself.
And, more generally, Jesus told his disciples to make disciples of all nations, baptizing them…, and teaching them to observe all that He has commanded.
There is, to me, nothing less than internalizing all that Jesus taught, and all that is contained in scripture.
Having said that I note that Judaism at one level recognizes 613 commands in the Old Testament and then they have something like 10 more rabbinic commands.
I don’t know that anyone in Christianity has organized into a coherent list the commands that Jesus is referring to. Moses is credited in Deuteronomy has encouraging the Israelites that obedience is within the domain of their free will and intellect.
The commands of Christianity seem more open-ended and almost unending in number. The catechism surely does not list a guide to all human actions. As lengthy as it is, its scope is vaguely “what we believe.”
