Hi: I've not been impressed with the look of viburnums in online pics; might have to rethink them. I have thought about evergreen Rhododendrons and might use some. Our soil pH is fairly close to neutral, as I recall. I don't want to completely hide the fence; that type of fence needs patching up from time to time, and I'm pretty good-sized; trying to crawl through a dense hedge would be a but much. I don't mind seeing some fence here and there; the shrubs through break it up & distract the eye from it. We have a septic tank & leach field the side of which extends out maybe to that last Euonymus bush (and then runs across the yard, not long-ways); I don't want things that get way high, since I figure their rooting systems will be more elaborate. Since the fence is about 5'4" tall, a shrub or small tree needing be very tall, and since many shrubs are about as wide as tall, I'm leery of getting big stuff. Basically, I like planting shrubs 2 or 3 feet from the fence; I don't want to have to plant 5 or 6' out from the fence, and take up a lot of yard space. The shrub row will also look strange if some shrubs are 4 - 6' tall, and a couple are 20' holly trees, for example. Hence my preference for a pyramidal short holly, rather than a round bush (plus I like the pyramidal look better). The Emerald Green Arborvitae get 12 - 14' tall, they say, but are there for a reason; kind of like I'm holding my hand up to block the view of that dog kennel. Richard.

Once again, a trip to a good local nursery should provide you with many choices, specially at this time of year when many of these places feature fall planting sales. You could consider a collection of dwarf conifers, which offer a wide array of shapes, sizes and foliage color. Broadleaf evergreens I particularly value for extremely low maintenance and all around good looks are Viburnum tinus 'Spring Bouquet', 'Newport Dwarf' escallonia, various nandinas, Cotoneaster glaucophylla, Euonymus japonicus var. microphylla (boxleaf euonymus - assorted variegated forms to chose from) and hebes, but there are scores of others. And there are many deciduous shrubs that offer stunning fall color or late season blooms. Most of these will not offer too much interest during winter but twig dogwoods are standouts and oakleaf hydrangeas generally hold their richly colored fall foliage well into winter.

Portuguese laurel has reddish petioles and terminal twigs, which I just don't see here. And in the OP's photo, even though it's far away and blurry, the new growth buds are pointed -- like in oak. But again, a closeup would really help! Here's a closeup of Prunus lusitanica -- note the reddish petioles and terminal twigs. Terminal dormant buds are not as prominant as in an oak. I would also think Prunus lusitanica would be really close to blooming about now in Portland? Here are the prominant swelling new buds and lt. green to yellowish petioles of Q. myrsinifolia in Spring:

I know you say that, Gardengal, but I grew up in a zone 5 midwestern town and saw many years worth of established Hick's yews blasting out upward growth every Spring. Later, throughout the summer would come more, and all this easily added up to a decent foot of growth. Where you are, 4" to 6" may be all you get, but it's not what is typical of Hick's in the upper Midwest. Here's a picture I snatched off of Google and you can see that there is easily more than 6" of new growth. It is not fully expanded and will become even taller. It is merely one flush of growth whereas there would be 2 more lesser ones coming before the summer growing season is finished. It adds up. It really doesn't matter what "reputable conifer sources" say when one can see endless examples to the contrary right in front of their eyes.
