I can appreciate asking questions and researching. But also, know that you can theorize, hypothesize, and what-if something to death.
Here is my advice to you. Run 5x5. Or 5 3 1. Or a hypertrophy program. Or whatever. Pick a program. You will 100% see results if you run it faithfully and consistently. Seeing as you're new, you will grow and you will get stronger.
I want you to run it for 6 months.
You want to grow and get stronger? 6 months should be a fraction of the time you're anticipating dedicating to the lifestyle required to really progress and get better. 6 months are going to pass anyway, how it passes is up to you.
During this 6 months, workout consistently. Eat consistently. Train consistently. You will have to take a few deloads. You will have to break through a few plateaus. You will really learn how your body responds to a constant stimulus and your diet.
At the end of that six months you will be in a VERY good place to critique the program you ran for 6 months. You will know exactly what you want out of your next program, exactly your weak points. You'll know what you're good at and what you need to work on. You'll be able to set intelligent and informed goals. You'll know that you can commit to a goal.
I would advise against jumping from program to program, second guessing yourself, switching from strength to hypertrophy frequently, and definitely when starting out. Pick a program and run the fuck out of it. I think the insight you'll gain from that will be rather vast.
