How should a shell fit? I can't decide between a large or an extra large. Is it best to have ample layering room or should it be tight and form fitting? I can't decide whether to go up or down.

My advice is to size up, especially if it's a shell that you'd wear in the winter months. You want enough room under the shell to accommodate a puffy, insulated jacket for skiing, mountaineering, or just cold weather camping.
There's really no downside to having a little extra room--except that you won't look as svelte in your hero shots.
The only exception is if you're looking at soft shells that have a little stretch built into the fabric. With these jackets, a snugger fit is okay, because they won't bind you up as you reach for a handhold or swing a trekking or ski pole.
