Access to HTTPS transactions for a domain you do not own requires the
SSL-Bump feature to decrypt ("bump") the TLS layer.
You could use cache.log with "debug_options ALL,1 11,2" configured to
log the transactions. However an ICAP service or eCAP module that does
both the record and analyze for you is probably better.

Please be aware:
That statement conflicts with the stated purpose(s) of your plan.
Personal data *will* be part of the messages you are decrypting and
recording for analysis. Further, to perform targeted reports such as
described you must also associate the data with accounts somehow.
