Beginner Workout Advice Needed

Started tirz today and dr said it’s important to get some weights type exercise in. I’m 40 lbs over goal weight, 46 y/o, never been super fit but at my healthiest was doing 30-60 min of cardio up to 5 times a week, did regular pilates & yoga. This was over 10 years ago though.

What are some of you doing to get started or where did some of you all start in terms of workouts? Any advice would be appreciated!
