I mostly agree; however:
- Buying a Wall Connector and setting it up on an over-40A circuit will help to future-proof the installation -- @Beck28 will be able to charge at faster rates if/when the SR+ is replaced by a more-capable car, or if/when a second and more-capable car is added.
- A Wall Connector on an over-40A circuit will be able to charge visiting friends' or relatives' cars at a higher rate (if they're more capable, of course).
- @Beck28 hasn't said where this installation is. As @TydalForce notes, the Wall Connector is rated for outside installations, whereas the Mobile Connector isn't. This makes the Wall Connector a better choice if the car is to be charged outside.
- There is value to having two EVSEs, both so that the Mobile Connector can be carried with the car at all times and so that one can serve as a backup to the other.
For the most part, these issues are minor, with the possible exception of outdoor installations, but they do deserve mention and consideration. These issues' applicability to specific people varies. There's also the question of whether a NEMA 14-50 outlet is currently available. If so, and if charging will happen in a garage, then using the existing NEMA 14-50 outlet with the Mobile Connector that comes with the car is more likely to be the way to go. If it will be necessary to install the NEMA 14-50 outlet, though, then the added expense of a Wall Connector instead of a NEMA 14-50 outlet may not seem so bad.
