"I ended up making a sacrifice- Windproofness. Instead, I'll supplement my fleece with a windshirt."
Windproof fleece is terrible stuff. Like softshells, it is fine for commuting or running errands around town, but is just doesn't breath well. A windshirt layered with a fleece and base layer is great for cold damp conditions.
IMHO, any of the light breathable fleece materials will work. Add Power Stretch to R1 and the rest. You can wear them comfortably under your rain shell too, adding warmth and moisture transfer and getting the cold rain shell off your shoulders and arms. You'll like your fleece for sleep as well.
I like a full zip hoody for all-around versatility. Vests are my favorite summer day hike backup insulation; my Power Stretch vest is just 8oz and takes up little room. You can find used 200W items for pennies.
