I’d say dumbbell training is one of the best ways to start lifting weights as a weightlifting beginner. Dumbbells are versatile and allow you to build strength and muscle without a gym; you can also still focus on gradually making exercises harder to produce results — something called progressive overload.
I always choose free weights over gym machines because they “force” you to work your core muscles harder with less support. As a personal trainer, I see many people overcomplicating things in the gym, and it’s no surprise, given the wealth of information now available at our fingertips.
