I'm a little surprised buxus doesn't make it, but I'll have to review it - there are different varieties.
There's also ilex vomitorius, sounds horrible but is "cute" - that I'd want to look up. Euonymous, which I've almost never specified, I'd have to look up.
Swimp, I'm not clear, are you looking for a sidewalk border plant, to make a line.. even a bushy not very pruned line..
or a low shrub that spreads (hmm, thinking one of the whatchacallits, cotoneaster)
Littlek and Green Witch know shrubs in your zone better than I do..
