One thing to keep in mind is the amount of sunlight that will enter the openings. They must get some direct sunlight for any kind of food plot seed to do well. If you can open the canopy a little more it would help. Logging roads could be good places depending on the amount of sunlight they receive. If you only have small openings I would concentrate on attracting deer to them. With such small plots you may not be influencing the nutrition of the deer very much.

Clover is always a good bet, and for fall atractants you can't beat a good brassica. I bought some seed and kept it for a year, and it came up OK. Remember, Mother Nature sprouts seeds that are years old, but generally there is a decline in viability as time goes on.

Finally, take care of those forgotten apple trees. Fertilize and prune them to help them produce again. Cut out all dead and diseased limbs, and any limbs that are touching other limbs. Fertilize them in early spring with a 10-20-10 fertilizer, and you may be amazed at the results.
