Dear Matt,
It is a good idea to leave the leaves where they fall as they will decompose (very slowly) and add nutrients to the soil. Oak leaves are notorious for not decomposing very quickly but they will. They will also keep your weed population down without any sprays.
If the rhododendrons are healthy, no notching of the leaves, or other insect pests, you can leave those leaves as well. Leaves are a natural mulch and will keep the soil warmer which will help if we have another 'ice' spell.
The leaves will also bring in decomposers from microscopic organisms to earth worms. Leaving the leaves intact (no mowing) gives a home to many of our predator insects, butterflies and pollinators who need habitat to overwinter. Habitat includes dead or decaying wood as well.
If you have bulbs, Hostas, ferns in the area, they will be able to break through the leaves even if you have quite a bit on the ground.
During the hot summer months, the leaves will also hold more moisture in the soil. The leaves will become your ground cover. If you wish to retain the ground cover, rake the leaves off of it.
I recommend 'leaving the leaves'.
