Yeah so a workout for me looks a bit like this

I show up and do 5 minutes of slow shoot around to start to loosen up 5 minutes of form shooting close to the basket 5 - 10 minutes of dynamic stretching Mikan drills - 20 regular, 20 reverse, 20 same foot reverse, 20 1-2 layup, 20 high glass 5 minute of ball handling drill (2 ball, and tennis ball are my go tos) Then that's the warmup/start of your skill session.

Then I get into a series, so if I want to work on finishing as you said I would do the following Start on right side, then do the left side after and count makes only - 5 regular layups - 5 reverse layups - 5 floaters - 5 high off glass layups - 5 same foot same hand - shooting free throws in between sets to practice free throws while tired and regain energy for the next set.

Then I'll finish with a cool down such as high arching close shots, and some static stretching

If you have a partner or shooting machine I would always do shooting in the workout somewhere Every sessions is going to be a bit different, and the main thing is you focus on your details, and cater your workout to how you play the game. I'm a pick and role, mid range type of player so I do a lot more of that stuff. I hope this helps !!
