We are fortunate to live in times where there are myriad evidence based resources online.
If you are looking for Hypertrophy (adding muscle) specifically I would recommend Renaissance Periodization (Dr. Mike Israetel) and Jeff Nippard on YouTube or their websites.
If you are looking for strength or general wellness I can not more highly recommend Barbell Medicine. I've had great success with several of their programs and my friend had tremendous success running their beginner template: https://www.barbellmedicine.com/shop/training-templates/strength/beginner-template/
Even if you don't buy a template they are a wealth of great information that is freely available.
Best of luck and congrats on taking that step!
Roberta "Bobbie" Draper from The Expanse was the first to jump into my head.
