I use a simple timer to do much of that

When <event> start timer
When <event = timer expires> do <action>

Typical example from one of my installations:

16.    WHEN ARM AWAY
         AND IF DARK
             THEN Laundry Room Light ON
             THEN Exterior Front Door Light ON
             THEN Exterior Front Patio ON
             THEN Garage Overhead Lights ON
             THEN Detached Garage Front Lights ON
             THEN FL - Exit Light Delay Timer ON FOR 5 MINUTES
17.    WHEN FL - Exit Light Delay Timer OFF
             THEN ALL UNITS OFF
