If you are "arriving" at 1950 there is no way that you will be in time to board a plane leaving Paris at 2045. 'Arriving' often means when the plane touches the runway and in my experience is usually late and almost never early. Deboarding and customs will take at least a half hour. Most flights require you to be in the boarding area at least 20 minutes before boarding ... so no time to transfer terminals, check in, and go through security.
There are no other transport options ... everything shuts down for the night.
Your choice of hotel might depend on your transportation choices for the next day. Get something close to the departure station so that finding your way in the morning doesn't cause a problem.

There are at least two viable options for getting from Paris Charles de Gaulle (CDG) airport to Saint Jean Pied de Port (SJPdP):
a. Fly from Paris to Biarritz and take the train from Bayonne to SJPdP.
b. Take the train from Paris to Bayonne and transfer to another train from Bayonne to SJPdP. Stations in Paris with trains to Bayonne include: CDG 2, Gare d'Austerlitz, Gare Montparnasse, and Gare Massy.

~Option 2 - Train from Paris to SJPdP.
TGV trains travel towards Bayonne from three train stations in Paris.
a. There is a TGV station located at Charles de Gaulle Airport Terminal 2.
b. There is a TGV station located at Gare Montparnasse in central Paris. There is greater frequency of service from Gare Montparnasse than from CDG 2.
c. The tracks from CDG 2 and Gare Montparnasse converge and TGV trains from both stations stop at Gare Massey.
SNCF TGV trains leave from Paris enroute to Bordeaux or Irun. Often there is a transfer required at Bordeaux. TGV trains from Bordeaux terminate in Irun. TER trains from Bordeaux terminate in Pau or Hendaye. If your train is bound for Pau another transfer is required at Dax. Trains bound for Hendaye or Irun stop in Bayonne.
SNCF Intercites night trains travel from Paris Gare Austerlitz to Hendaye and stop in Bayonne.
SNCF TER train #62 travels from Gare Bayonne to terminus at SJPdP
You will get limited results if you try to find a schedule for a train from Paris to SJPdP. I'd suggest planning your trip from Paris to Bayonne then Bayonne to SJPdP.
