These are all helpful entries, and to a large extent I believe that begginners should try and establish time in the trenches and discover what particularly works best for you.
Experiment with a range of these set rep pattern but be wary of fatigue and results they illicit.
An interesting point I would add is that set/rep protocols are important but they need to be seen as only part of the process, exercise selection, lifting techniques, rep cadence (speed of the lift), and also the amount of rest between sets.
My advice is stick to programs designed by professionals, and try to gain practical knowledge and theoretical knowledge of why and how different strategies work. This will allow you to similtaneously develop towards your goals as well as being in a position to adapt and create your own programs.
In short this is my personal step by step reccomendations for the direction of an autonomous weight trainer
1) Find a proffessionally designed program for your level
2) Whilst training be wary and reflective of the strategies that work for you
3) Study the underlying factors and reasons for training in specific ways
4) Get to a stage wherebyyou can adapt proffessional designed programs to better facilitate your goals
5) Design your own programs
Always be open to suggestion and really focus on weight training across all spectrums, nutrition, psychology and physiology to name a few.
