True cedars and incense cedars will not grow in Minnesota (too cold). But the common name White cedar is a vernacular name for arborvitae here in Minnesota, especially the wild arborvitaes. Your brown "berries" are actually the seed cones, and prove your plant is an arborvitae. Eastern Red cedar is actually a juniper and has seed cones that actually do look like berries that are blue. As you have discovered, there are many available forms of arborvitae, from large trees to midgets that only grow 10 inches tall. Technito has a foliage growth pattern unlike your specimen, but it matches the Holmstrup cultivar very well. And Holmstrup has been in the trade for a long time, while Technito is relatively new and not widely available, even though it comes from our own Bailey Nursery here in Minnesota.
I live twelve miles west of Paisley Park.
No more traffic jams there, but there are still a lot of people.
