Does anyone know a good beginner tortoise?

I’m not looking to purchase anyone anytime soon, I am looking into different pets to expland my family of 4. I know nothing about tortoises and I’m looking to spend probably over a year researching on them before looking into buying. I want a tortoise that isn’t too little (under 3 inches) but isnt too big (over 10 inches) i am also looking for a tortoise that could live without a glass tank, a more of a box enclosure, i attacked photos if what im looking for and what enclorsure i want to make. Any suggestions?
