For transportation from CDG into Paris, consider:
1 - Taxis Parisiens from the official taxi stand. Do not accept offers from clandestine drivers soliciting from within the terminals. Taxi fares are fixed at 56€/65€ to the Right/Left Bank respectively (for up to 4 passengers and luggage). There is a 5.50€ supplement for each additional passenger from 5 to 7. Drivers are not tipped and accept Visa/MC.
I recommend official taxis as they have access to special routes/drop off points, HOV lanes, and bus lanes that VTCs (Uber, Bolt, Freenow, private car) do not. Taxis do not have surge pricing. Hand the driver your written destination. There is no charge for luggage.
2 - Train - RER B from either terminal 2 or Roissypôle. Includes any required connection to reach any RER/métro station - 14€. Follow the numerous signs ¨Trains to Paris". Fare includes any métro/RER/Transilien train connection required to reach your destination. Keep your ticket until exiting the transportation network.
