You're right, the results aren't predictable, as you've seen, since object-level effects are modified when compounded by an effect applied to a containing group. Color sometimes plays factor too.
But realistically, there aren't that many results that are useful. Generally, I've found the structural blends are most useful for masking objects and groups, while the imaging blends are more for color/visual effects, like the standard Photoshop blend modes.
