Yellow jackets can start holes in the fruit too. Purdue and penn state has some good articles for fruit growers explaining common insects.
Having a few green or yellow apples around helps too. Some insects look for the red.
My trees are young expect for a few old ones of unknown variety. The best looking fruit I have is franklin cider. Might be some wildlife value despite the excessive original hype about them. Thick skin is another characteristic to look for. I read enterprie has a good skin to it.

MY main goal is deer, cider, and apple sauce. Going to give sandbur's recommendation on leaving skin on ans straining the sauce free of peels. Be alot easier with second grade apples. Ones with damage like that. Cut it out, dice it up, cook it.
I got a few acres at home and a big hunting lease. For you guys with your own properties, make a few trees by the cabin, then put some more out back. Atleast you can play with some furit without disturbing the critter way in the back. Liberty and Enterprise are must haves and earlier apples too. Galarina I believe is a bit thicker skinned too. MY freedoms look beat up. trailman, kerr, chestnut, and williams pride are good ones. Hewe's was a very huge success back in the 1700's up to prohibition in the 1930's. They used it as rootstock too. Think that one is probably a good fighter. MAybe us hmegrown apple folks don't mind it, but it grew out of favor because it's a booze apple.
I have eating apples for me of various drop times, then after that I got zone 3 trees I can get scion from for camp.
