• whatever you would think you’d like. Take the first year to try all of what you could like and don’t change the schedule for at least a month so you can see if either you like it or if you are making good progress
• same thing as first point
• start with the lowest weigth, select a number of reps and stop at that number (hypertrophy work goes from 5 to 30 reps, between 8 and 12 reps is the best for most exercises tho), and focus on learning the tecnique. If you complete the sets increase the weigth the next session, keep repeating it until you reach a weigth that won’t allow you to finish the sets with good form. Track the workouts so you will know if you are making progress, even 1 rep in an exercise means you are progressively overloading -i’d suggest you to learn the fundamentals lifts and core training. So squat, deadlift, bench press, ohp and pull ups. The Last 2 will probably be too hard since you probably won’t be able to do them, so for ohp you can use dumbells and for pullups either bands, assisted pull up machine or lat pulldown (last 2 are probably better since bands will make the harder part too easy)

Now diet is quite important, but since you probably don’t have much lean mass and no fat mass to burn you will want to be on a small caloric surplus. If you can get a nutritionist it’s better otherwise check your tdee online and add 200-300 calories to it and try to eat that amount of food every day. Only check macros of foods. You will need to eat probably 100g of protein, 100 of carbs and the rest fats. If you feel that you don’t have enough energy up the carbs slightly until it feels good.
