Hi Mike,

$ gpg --verbose --version

will tell you (after the cipher/algorithm and between ()) what is the
short code to use with setpref. Example for Cipher:

3DES (S2), CAST5 (S3), BLOWFISH (S4), AES (S7), AES192 (S8), AES256 (S9)

I might have misunderstood your question, so feel free to let me know
if you need something else.
