I don't have direct answers to #1-3, other than probably none are the "best" for birds, since one would assume you want to support native birds. To do that best, use native plants that those birds would expect to find food from. Of those you listed, V. setigerum (not a native) is the only one that reliably has fruit on the plant through fall and into winter.

Philosophically speaking, I think you deprive yourself of some great joy by predicting doom and/or gloom from VLB. This isn't a parallel situation to planting a shade tree that takes many decades to mature, fill in, and shade a site, only to be lost to DED, EAB, or ALB. Most shrubs (and certainly the viburnum species you listed first) perform and reward in very few years (1-5). Unless you expect to invest significant capital in the plants, you ought to go ahead and plant what you want to and enjoy the dickens out of them until VLB (if ever) shows up.

By then, it may not be the scourge in MD that it is in upstate NY/PA. There may be a control for it by then, or it may never even arrive in MD.

I'd vote for all the species you originally listed, with V. acerifolium and V. rufidulum as two more natives. Don't let the perfect be the enemy of the good.

Excellent reply above!
Also, AFA the natives to your State go, besides V. cassinoides, look for its "cousin" V. lentago (the nannyberry V.). As I have seen so far in a dozen or so years of gardening with this lovely and easy "bird hit", the VLB (we are in the Montreal, QC area) ignores it (and I am pretty sure the same goes for V. cassinoides).
V. lantanoides (AKA V. alnifolium) is charming and gorgeous (esp. at this time of year!), and is immune to the VLB. Not easy to find in nursery though, and requires acidic soil to thrive and fruit.
I have had good success so far at keeping my V. trilobum (the highbush crannberry tree, an essential sp. for late winter bird/cosmetic fruits) VLB-free in our VLB-critical zone, apparently, by treating it thoroughly against aphids with Safer soap, a few times during the growing season. "Fingers crossed", but it's as if the VLB hated the taste of the leaves thus treated. In Montreal, just across the river from here, park plantings of V. trilobum are horribly affected some summers, while ours thrive just fine!

Thank you again Viburnumvalley and thank you Roseunhip for setting my paranoia straight.
