I love my old workout. Its legendary on the internet. But its a lot of volume and hence time. Also not sure I can begin with it.
Its this -> https://www.muscleandstrength.com/workouts/dougs-4-day-split-workout.html
Did this in 2010/11
Looks good but seems paid and a lot of niche exercises, some machines might not be available. Plus actual stuff is paid.
Suggest something lol
