Dont complicate things yet. You don’t have the base, background or experience.
At the beginner stage of the game you need a linear progression program. I suggest you buy Starting Srength and Practical Programming for Strength Training both by Mark Rippetoe.
5/3/1 is good but progression is too slow for a beginner. It’s geared more towards an intermediate lifter. Plus the training weights calculate off a max which I doubt you could even perfrom correctly at this stage.
Westside (which I’m using now) is really designed for a more advanced lifter whose orm is dialed in and who can assess his weaknesses. Beginners have no weaknesses, theya re just generally weak.
For a good linear periodization routine study Ed Coan and Mike Bridges. I used their methods in the past with a fair amount of success.
If you are a good natural deadlifter and can tolerate a ton of work look up John Kuc.
