Thanks to all who have responded to my question privately or via OBOL. The consensus is that this bird is an immature Red-shouldered Hawk. In addition to the OBOL responses, other thoughts included:
The amount of dark mottling/barring below seems excessive for a young Broad-winged. Further, all the white barring in the folded secondaries is a better fit for Red-shouldered as is the mostly dark head. Another feature that almost always points to Red-shouldered is the comparative width of the dark and light tail bands. On Red-shouldered the dark bands are typically noticeably wider than the light bands.
Broad-winged never has pale spots on the secondary wing feathers, whereas Red-shouldered always has those pale spots.
