Took a few more pictures today and tasted the berries, maybe this will be helpful for identification.
Unfortunately I wasn't the one who pruned this plant earlier and I don't know what it looked like before pruning. I don't have earlier pictures from other seasons or with flowers, etc. I don't know if it was planted on purpose in the landscape from a nursery or if it was a volunteer gift from birds or other wild animals.
I crushed the berries and smelled them. They had no scent to me. I tasted a berry and spit it out. It had a mealy texture and almost no taste to me. The immediate aftertaste was slightly unpleasant, maybe a bit bitter or some unpleasant taste I'm not familiar with, and also maybe slightly sweet. Any taste was very faint and hard for me to make out.
These photos were all taken earlier today. The triangle ruler tool I used for scale is about 8 inches on the two shorter sides.
