I've heard that planting trees in the Sahara would be worse because since they're darker they would absorb way more heat.

Actually yes, planting trees (especially the wrong trees) is not always a good thing. Darker leaves will attract more heat (imagine if it was possible to turn the polar regions into trees - this would have a very negative effect).

Also mono cultures and replacing natural vegetation with man-made forestation can actually be more limited to the amount of carbon they can capture long term.
