The issue is that when I SFTP a file onto the server, the default umask

This doesn't match my experience.

pegasus:~$ touch foo
pegasus:~$ ls -l foo
-rw-r--r--  1 greg  greg  0 Oct 11 08:37 foo

pegasus:~$ sftp greg@griffon
Connecting to griffon...
Enter passphrase for key '/home/greg/.ssh/id_rsa': 
sftp> cd /tmp
sftp> put foo
Uploading foo to /tmp/foo
foo                                           100%    0     0.0KB/s   00:00    
sftp> ls -l foo

Perhaps your sshd daemon is being started with a umask of 077, which is
then passed down to the sftp-server child.  Examine your start scripts,
and see whether putting "umask 022" (or whatever you wanted) in the
sshd start script helps.
