If you need a car, EV is a better choice. At least it doesn’t spew fumes directly on the street, although it’s far from ideal since electricity generation and lithium mining are also polluting. In balance slightly less harmful than ICE.

Choose whichever connector is the most standard where you live. CCS2 in Europe, NACS in North America, CHAdeMO in Japan, the standard in China is usually listed as GB/T. No idea what is used in South America. The point is to make sure you’ll be able to resell the car easily in the future.
