That's also known as "maintaining a log book/console log".step 1, find a time machineHow do I know which files and configuration need to be copied? How do I find them?
step 2, go back in time
step 3, tell yourself to document every config file you change, so you know how to set things up again next time you install the OS
The difficulty in making *anything* "fool proof" is that any time you achieve that, Nature invents a bigger fool.
On a serious note...
Get another Pi and SD card. Set up (in turn) a test system that functionally replicates the attached hardware one of your working Pis. Load the current OS to the new SD card. Load in everything you think the Pi being replicated has on it. Test the new Pi/config. When everything works, swap the SD card into the "production" Pi and move on to the next Pi. Take full notes and repeat as needed. Plan to do this every two to four years.
