Seriously though you're overthinking this. Having a Roth is nice, especially if somebody will be matching ((or just plain making) your contributions, which seems to happen for many younger people here. Keep it all in a target fund or total market fund. Nobody knows where our QQQ idea came from but I suppose if you want... whatever. Just pick one thing and stick with it.
For taxable put everything into a bank or MM account of your choice. The rate doesn't matter at the amounts you have, but if you want to choose one with relatively high rates. Just don't waste time moving funds around monthly for .1%. You say you have no expenses but you do - someone else is just paying them. Some day they won't and you may have to use your savings.
What will matter is education and eventually employment and spending less than you make, not minor differences in how you invest.
At age 16, a Masters Degree in Engineering or Computer Science, etc, seems like a long way away and an extreme amount of effort that might not be exciting. But, educational levels and achievements like have lifetime earning's and career benefits that are immeasurable. Not everyone can do it. Hard work and perseverance for that long is not in everyone's mindset. Is it in yours?
