I dont know about Wolf River but Liberty and Arkansas Black are supposed to be very disease resistant. If they are labeled for your growing zone I would say they would be good choices.

Wolf River tends to be susceptible to Fireblight. Arkansas Black and Liberty shouldnt give you much problem.

Wolf River are great if you plan to do any baking/cooking. They are nice big apples (around 2 lbs if memory serves me) and have resistance to everything but fire blight.

Arkansas Black are pretty unique in their flavor and color, but often need to be stored for a few months after picking before you want to eat them. Otherwise they can have an off-putting taste. While in storage, they will develop more sugars and when they turn almost black, they will be ready to eat (some years they do taste good fresh, but most years they need to go into storage first). They also have a very long storage life, around 4-5 months and are supposed to have a very complex flavor to them.

And i don't really know much about Liberty, nothing about it really stuck out to me, so i never researched it or planted it (space is limited, so there has to be something that stands out for me to plant a variety). I have both Wolf River and Arkansas Black, and am in Nebraska, Zone 5b. Both are growing well for me, with this year being the first production year for Arkansas Black. I will have to wait about 2-3 more years for the Wolf River.

For apples, here is a great resource: https://orangepippin.com 

OSU has certain ones they think people not wanting to spray a lot should use for home orchards.

After reading more about the varieties, I went back to the store for Arkansas Black; but alas, they were sold out. I did get the last Wolf River. Maybe they will have it next year.
