I'm really struggling to think of a strength training scenario where your heart rate wouldn't be elevated (thus increasing blood flow). Consider a max. back squat, where all your muscles are contracting to the maximum degree that they can for several seconds. I'd say that'll make your heart pump.
(Thanks for the citations. That's awesome, and I wish more people would do it.)

Weight training and cardio training have different effects on the heart. Weight training forces the heart to pump against resistance, leadening to a thickening of aorta walls. Cardio requires blood to be circulated more frequently, leading to an enlargement of some heart chambers.

The effects I'm talking about are not during the actual exercise, it's more long term. Note that even though they are long term (~12 weeks I think) they are not permanent, if you stop exercising soon there will be no benefit.

I've noticed that when I run my breathing speed and heart rate increase up to 5 km, then stays pretty much constant. I don't know why this is though. If you do strength training you probably stop long before this point.
It has the additional benefit that it alters your mood, aerobic exercise makes you happy :)
Strength training may boost testosterone, but the effects of aerobic exercise is well established. Several comparisons have been done between aerobic and strength training and the conclusions have been that strength training have little effect on executive function.
My source for this is the book "Brain Rules" by John Medina [1]. Also check out his presentation on exercise [2] and his Authors@Google talk [3].
