How does this itinerary look for Mexico City?

I am going to Mexico City in one month. So excited for the trip but I am really having serious paralysis by analysis with planning the trip.

Day 1 - Arrive 2pm, check into hotel, relax, go out to eat somewhere

Day 2 - Centro Historico, Zocalo, Palacio Nacional, Palacio de Bellas Artes

Day 3 - Teotihuacan tour

Day 4 - rest day, walk around, eat, maybe see some live music or something

Day 5 - Xochimilco and Coyoacan

Day 6 - Bosque de Chapultepec and Anthropology Museum

Day 7 - Tolantango full day tour (maybe?)

Day 8 - check out the mercados (if it hasn’t already been done on an earlier day)

Day 9 - Depart

I think the Tolantango tour might be really cool but from what I’ve read it isn’t really a “must see.” I do like the outdoors and I live in a big city so might be nice to get out of the city.

Does anyone have thoughts on this? I am just curious because this is my first real international trip. I’m excited but a bit overwhelmed

Also, I speak decent Spanish but here in the US I haven’t had many opportunities to practice speaking. I would love to become more comfortable speaking Spanish on the trip. I can understand and read it very well
