Hi Jim,
Where can I find detailed info or guidance on the use of the options, -C
etc that can be applied to wsprd?
For information more detailed than already provided in the help message,
you'll need to read the wsprd.c source code.
The default value for the maximum number of decoder cycles is 10000. I
do not know why you might think 500 is used here.
You will find that decoding performance depends only weakly on the value
chosen.
If you have a specific question, please feel free to ask.

yes.... a bit more info would be desirable...
for example the default that wsjt-x uses for -C is 500 yet wsprd itself
has a default of 10000

Are you looking for more than this?
/wsprd: invalid option -- '?'
Usage: wsprd [options...] infile
infile must have suffix .wav or .c2
Options:
-a <path> path to writeable data files, default="."
-B disable block demodulation - use single-symbol noncoherent
demod
-c write .c2 file at the end of the first pass
-C maximum number of decoder cycles per bit, default 10000
-d deeper search. Slower, a few more decodes
-e x (x is transceiver dial frequency error in Hz)
-f x (x is transceiver dial frequency in MHz)
-H do not use (or update) the hash table
-J use the stack decoder instead of Fano decoder
-m decode wspr-15 .wav file
-o n (0<=n<=5), decoding depth for OSD, default is disabled
-q quick mode - doesn't dig deep for weak signals
-s single pass mode, no subtraction (same as original wsprd)
-v verbose mode (shows dupes)
-w wideband mode - decode signals within +/- 150 Hz of center
-z x (x is fano metric table bias, default is 0.45)
