I was hoping for a bit better performance. Any suggestions for similar that could max out 4-5 drives, maybe add a M.2/U.2 for caching (or 2), and handle 2.5 gbit ethernet?

5 HDDs and 4 SSDs for caching, with 10gbit fiber or 2.5gbit ethernet.
I have 40 terabytes of storage in mine(21TB free). If I ever fill it up, I'll probably buy an actual storage server with ~500TB of drives.
