You'll have a mobile phone with you, I assume. Take a charging cable so that you can keep it topped up, and therefore available if you do need it. The USB port will likely be in the glove box. Be familiar with the dashboard warning symbols in case any appear. The link below is to the MY23 CX cars, but the MY25 cars will likely be 99% the same.
As sospan says, check the oil level once the car has had the run and the engine is up to temperature. At that mileage I would expect it to show 4/4 (full, green).
The fuel could be stale, at the earliest opportunity fill with E5, and I suggest using E5 for the first few fills. E10 should be OK if you are using the car regularly but it is more likely to absorb water and the ethanol / water mix can cause deposits, which you don't want in the fuel system (ask me how I know ...).
