Hah, I wish I had any pro tips to give! Most of the time I just wing it.
I have some routines, which I guess could be considered tips:
- Grab the wrench from the garage in your safehouse. Good melee/distraction + can be used to sabotage stuff.
- If I am in need of money, I usually choose the assassination syndicate. The optional objectives are close to Silent Assassin playstyle.
- Always take care of alerted territories first, I usually don't even try for the optionals. Just quickly get them over with and continue with the normal territories.
- Assassins always carry a silenced pistol, good way to get one.
- No two showdown suspect have the same looks and tells. As long as you have a visual on a suspect (the icon over their head is visible) you can see their tell when they're doing it. Good way to eliminate suspects from distance.
