The soil I garden on is neutral rather than acidic, so I can't help with that part of the question. The plants I've grown on neutral soil that the deer have left alone include:
Rosemary, nepeta/catmint, choisya, peony, feverfew (tanacetum), acanthus, irises, snowdrops, daffodils, abelia, brachyglottis, geranium, bidens, lonicera (shrubs and climbers) abutilon, euphorbia, verbena bonariensis (but not other verbenas), ivy.
I also found they didn't eat rosa rubrifolia, and I believe there are some other roses they leave alone. I think they leave alone stinking hellebore (h. foetidus), and they don't eat the leaves of h. orientalis, but then they eat the flowers. The viburnum tinus leaves remain untouched, but in really cold weather, if they can get to the bark they chew that, as I found on one which I'd cut all the lower branches off.
The seem to be curious, quite often uprooting but not eating something they haven't seen before, which is infuriating. They will also eat young tender emerging shoots of plants they leave alone later in the season - daylilies for example.
I had some success spraying with Grazers, which seems to put them off. Hope this helps.
