All plants require maintenance. Water, fertilizer, weeding, pruning, and mulch. And unless you spend $$$ and buy large plants to start, you will have to wait several years until the grow to block out the neighbors
I would suggest a fence with a few plants in front.

How's the drainage? I have clay soils and grow some 100+ different species of trees and shrubs. Never fertilize, do not mulch. Bought 10 acres of a place with about 4 trees. Something like Chionanthus virginicus grows fine, is deer resistant, but needs well drained land. It absolutely needs sloping ground if you have clay. The shape is a mound about 15 ft. tall (after about 10 years from a sprig). Native evergreen Hollies (like Ilex opaca) make a decent screen after just a few years. If you want to put up a trellis, you can hide anything in 3 years with Aristolochia durior (macrophylla is a synonym). Doesn't spread all over, thrives in shade that is not to deep.

If your idea is to plant it and forget it, forget it. Even the best situated, native or foreign plant needs a pruning to eliminate crossing or dead branches. Pruning to shape is also often needed. Spending every weekend is not required, but 10 hours/tree/year should be expected. (Pruning, weeding etc.)
