The deer here in SC LOVED my blueberries, until I fenced the bushes in and the deer out. Cranberries might do, as might one of the deciduous hollies, for berries - you would need a male to get berries. Inkberry is an evergreen holly that might work, although the dark berries aren't especially interesting. Either red or black chokecherry is a possibility. Another might be either grey or silky dogwood, or red osier/red twig dogwood, Cornus amomum, recemosa or sericea, respectively. Hinoki or Sawara false cypress might have several cultivars of a size and shape that suits, taking both sun or part-shade. Another evergreen, although more for the sunny spots, would be a Juniper cultivar such as 'Grey Owl' - not all junipers are low and spreading. Mountain Laurel is a broad-leaf evergreen that might suit for the sunnier parts - it will take shade, but will flower less for you than here, where it needs shade - there are other colors of flowers in the cultivars than just the pink/whites, shading into reds. And some of the native azaleas, both the evergreen and deciduous, might well add flowering interest - some also are heavily scented.

For summer fruiting viburnums, the Arrowwood Viburnum clan (Viburnum dentatum) can be an excellent choice. These plants reach 8-12' easily (and they don't grow on to 25-50', no matter how old they get), flower prolifically with white flowers, and set heavy crops of dark blue fruit. Your important consideration will be selecting two differing clones of the species, so that you have adequate cross-pollination opportunities. Check for older threads on this subject, as suggested before. There are several. I'd suggest a couple selections from choices like Red Regal, Cardinal, Indian Summer, Red Feather, and Raspberry Tart for reliable fall color in the reds/oranges range. Another excellent species (highly underused...) is Viburnum cassinoides. There are a handful of fine selections in this species: Buccaneer, Challenger, Defender, Endeavor, Freedom - and maybe more by now. This species has sturdy foliage which generates a range of fall colors with red, burgundy, orange, and yellow highlights. Fruit clusters mature from green through cream, pink, reddish, to blue. Other species likely to perform well in Michigan include Viburnum nudum and Viburnum trilobum, comfortably in the size range you mention. I also really like Viburnum sargentii and Viburnum sieboldii, which can get quite a bit larger. All the fragrant forms are very nice plants, too, but are not often grown for fruit display. Doesn't mean you can't, however. Select a nice Viburnum carlesii, and pair it with Viburnum x juddii or Viburnum x 'Cayuga', and you should have a durable show of reddish fruit that will mature to black by fall. If you gave more information about your site conditions (exposure, soils, moisture, etc.), the list could be tailored more closely to suit. I don't personally think you could go wrong with anything you choose - the genus is THAT good.

Yes, there are trees that have dark red leaves all year. Even a few that survive in Wisconsin. Not aware of any that have fiery red leaves all year. Alas, sugar maple and red maple (despite the name) do not. Sugar maple is fiery red in the fall but green the rest of the year. Red maple is bright red in the Spring and (if you are lucky) in the Fall. Green in between. Ditto for Nyssa sylvatica 'Wildfire'. As far as trees that have dark red leaves all summer... If you have the space and patience, copper beech is...the best. It just kind of is. Totally breathtaking long lived tree with deep red leaves and perfect form. Should survive your cold winters. Unfortunately they are somewhat slow growing and difficult to transplant. Japanese Maples are kind of the standard for this use. If you want something smaller, some kinds of crabapple, like Prairifire give you flowers and red/burgandy leaves. Leaves may turn green in the summer. Purple Leaf Plum would also give you flowers and red leaves. Could you look up your USDA zone? What is your soil like? Sandy, salty, compacted, muddy, clay, alkaline? How far would this be from the nearest road house or power line? What threats will this tree face? Road salt, wind, gypsy moths?

I found Latham is very protuctive / small but tasty...Purple Royalty could be nice for you if you don't like much acid...a little bland. Fallgold I got rid of and just keep Honeyqueen. The others I don't have so I can't comment, my best red is Killarney, Chief and Souris. They don't need good soil...and if you're too old to prune out...no need to do that as long you can walk your lawn mower up and down the row and trim always close to the row..not letting the row go wide, it only needs a foot wide...this still gets air moving and light in... and maybe tie a couple of twines along the side so they don't flip over..eventually old canes will disintegrate on their own.
