Garage[1] lacks a web UI but I believe it meets your requirements. It's an S3 implementation that compiles to a single static binary, and it's specifically designed for use cases where nodes do not necessarily have identical hardware (i.e. different CPUs, different RAM, different storage sizes, etc.). Overall, Garage is my go-to solution for object storage at "home server scale" and for quickly setting up a real S3 server.
There seems to be an unofficial Web UI[2] for Garage, but you're no longer running a single binary if you use this. Not as convenient as a built-in web UI.
