I have several of these in my front yard, growing in and around very large azaleas. I have recently moved here and do not know if they were planted intentionally or are accidental native. They are currently 6-12 feet high, growing in clumps more like a bush. However, one near the house is probably 25 feet (or more) tall, with single trunk, more like a tree. Leaves are 4-7″ long.
I am not at all certain of this one. The closeups you sent look a lot like the native Symplocos tinctoria, which flowers very early in the spring, but I have never seen one this tall. If I find out more, I’ll let you know.
