What extra missions do you recommend after completing the campaign ?

A bit late to the party, I know.

I just finished Hitman's campaign from start to finish (before that I did some missions in a different order).

Now I feel overwhelmed by the amount of content there is. Do you guys know what extra missions I should do if I want to go from worst to best ? Do i start with the seven deadly sins ? Patient Zero ?

Consider I have every expansions (I lack some elusive target arcade missions that I haven't bought but that's it)
