Just an FYI:
The government head of CDMX, Claudia Sheinbaum will resign on this Friday to campaign for ranking in the upcoming Presidential election. She was responsible for implementing the CDMX cable bus system and upgrades to the Metro/Metro Bus systems. I mention this because the newest cable bus route #3 (the one that many visitors will ultimately use) is still slated to be inaugurated and open this December 2023 and is supposedly still on schedule regardless of her departure. The fare for the cable bus system is 7 pesos on all routes and accepts the metro card.
Below is the map of the new route, #3 that will travel over Chapultepec Park between Los Pinos and Santa Fe city limits (5.4km):
