If you had fully read that post by Jim you would have seen he said that he almost always recommends people just run the base program by itself.
Just do the base 5/3/1 program found in the second edition book. Pick an assistance template and get to work. If you are a true beginner you probably don’t need to worry about supplemental stuff like FSL for months or maybe even a couple years.
There are several beginner routines and they are all solid. The one on the website is a full body routine so you just hit the lifts more frequently.
You could do that one or just the base program. Whatever you choose to do, do it as written.
First and foremost, follow the core principles of the program and you will make progress.
