I recommend you buy the original adapter, with original cable. The most important part is the cable. With original cable it's guaranteed that the dimensions of the cable plug will be exactly as it needs to be, a slight difference in those dimensions will damage the female USB C port in your phone.
With third party or second party cable, chance of slight differences appearing is high.
The reason for the original charger is, that it's female port dimensions is guaranteed to be on spec, the third party charges can damage/wear out your original cable male USB-C head, it's okay as long as that end always goes to the third party charger side, but with USB C you can use each end on either, so that side when plugged into phone cable damage your phone female USB C port.
Even though USB C standard is universal, all manufacturers are following that spec, but I know instances where on iPhone 15 series the port on phone have died prematurely, the users were using third party cable.
It's doesn't mean that all third party cables will be out of spec, it's just that the chance of them being out of spec is higher than the original cable.
