My favorite introduction to this is the book "The Barbell Prescription", together with "Basic Barbell Training, 3rd Edition". They got me out of just getting sweaty and tired in the gym to actually training and increasing my strength.

The people behind these books also run the YouTube channels https://www.youtube.com/@GreySteel and https://www.youtube.com/@startingstrength, respectively. Lots of highly educational videos on these!
