To me, depends on use, quality, and cost. Agree the heavier duty isn’t going to charge faster.
But, heavy duty can have better insulation, better plugs/receptacles, and more strands of copper in case some break while flexing. So, potentially a bit more resilient.
if it was something I wanted for travel to keep in the car all the time, I’d go lighter. If it’s regular use in a fixed location, I’d round up. There is also a law of diminishing returns, so I wouldn’t go heavier (but I do have a 50a 25ft cord I left at relatives house to access a 6-50 at the back of their junk filled garage the 2-3 times a year I visit).
So yes, 12ga is enough. 10ga is a bit heavier but won’t change the charging in a measurable way. Personally I’d get 10ga if it’s out a lot and 12ga if it’s a travel cord.
