Ideally, you want to put exercise involving significantly different energy systems as far apart as possible.
For every form of activity there is a fitness effect and a fatigue effect. The fatigue effects of some forms of exercise will reduce the effectiveness of others.
In regard to different energy systems:
Best case...alternate days
Next best case...at least 6 hours apart
Next best case...long-term energy systems after short-term energy systems in the same workout.
Strength trainging = short-term
