For vision i would say make any text large, look at colours which are better for those who are colour blind. Make sure to write that this was the reason behind the colour or the font.
I would also speak to your teacher and ask them would this be possible/ feasible. As some schools may have limited materials/ equipment/ machinery to help manufacture the product. Finally, by asking your teacher they would be aware of this is too complex, should you reduce some elements etc, and maybe even how you could showcase this.
I apologise that this doesn’t really answer all of your question, but I would definitely encourage you to speak to your teacher, as they will be more skilled than most of us students on here
