Hybrid Willow Medial Cuttings Question

I've recently planted about 40 hybrid willow cuttings for privacy and block some wind eventually. 2 rows, 5 feet apart in row, 10 feet between rows. Some are from branch tips, but a majority are medial cuttings. The medial cuttings are between ~15-20", and I likely have too many nodes above ground based on researching.

My question is, which I can't seem to Google with proper wording, will these medial cuttings grow to have a single lead and grow into a large trees with a solid trunk, or will these basically grow like a topped tree?
