What is the problem you are having with rclone?

When mounting a remote using rclone mount --vfs-cache-mode full and modifying a file, the file is immediately updated but the modification time is updated only after the file has been uploaded to the remote. In case of large files with slow internet this can break applications that rely on updated modification time.
