Classified of nymphs versus wet flies will probably be a matter of personal opinion. I prefer to think of it in terms of the bugs you are hoping to suggest. On my home trout waters which are tail waters there are a dozen or so different mayflies and caddis are available to the fish all year. The vast majority of the mayflies are clinger type nymphs with quite pronounced legs so soft hackles work well to suggest them drifting in the current. The caddis pupae can also be well imitated with a soft hackle drift and swing.
A number of the the mayflies could be imitated by a pheasant tail nymph tied with longer legs but a soft hackle is a quicker tie.
Add midge and bwo imitations and a few streamers and you have my home waters covered
