When I was doing a calisthenics rotation I was pretty much doing squats, pushups and pullups so I can't advise you on that so much. In between I would throw in some 'holding' ab work e.g. planks or hanging knee raises or whatever. There was a period where I would set a 30 min timer and do as much of a combination of pushups/pullups/squats as I can. Then the next session I would try to beat that number.
If your goal is to lean up, that's more a diet thing than workout. I don't think workouts determine nearly as much in terms of body appearance as a diet will.
That said, further to
@Squidward24's point, you will see the best strength gains from those compound lifts. Some people don't like this, but I'm a big fan of the 5x5. I saw my best strength gains through that and you will naturally gain some muscle as well (although slower than if you focused on hypertrophy exclusively). But diet is key to all this.
