The "Flight Evaluation Reports" from the Apollo missions have a number of data plots and tables from the missionsthat may help you.
Bob Braeunig developed a simulation that matched the Apollo 11 flight report rather well, which you may want to refer to; unfortunately he seems to have taken it down but it's available on archive.org.
You can probably find similar data for other NASA missions on ntrs.nasa.gov with the right google search terms. Commercial and former-USSR launches tend to be a little less free with their data.
