Any V6 non-TH with AD1 is plenty for you. And add the tow group if you're going to tow. Also, either a Latitude or Limited with AD1 will have a somewhat smoother ride than AD2 or TH. If you don't intend to go off-roading anyone who tells you that you need AD2 or a TH in Southern New Mexico is misguided.
And despite the Jeep ads, the vast majority of Cherokees sold are non-Trailhawk models, so buying a TH will actually hurt your resale value, especially if you're trying to get rid of it in Southern NM.
Agree up to resale...the rarity and public demand should increase the TH resale over the more common models.
