I'm really impressed, particularly at your age, that you are really willing to do the research and reach out to others with more experience for advice. In the end, you will be he one to make the final decision of what goes into your tank and the consequences both success and failure are yours. No two tanks are alike and there are those who can keep a McCosker's (one of my favorite fish) happy in 40 gallons and those that couldn't do the same in 100 gallons. It is an awesome hobby and constant learning experience. You seem to have what it takes to be successful in it. Good luck with your stocking plan and progress. Please keep us posted on how things are going.
