I'm on tapatalk at the moment so can see where are you are located. If you are in Australia or New Zealand the local SGZC12SG version comes with a 32GB SD card. The USA edition does not come with a SD card.
A poor quality SD card creates a huge problem,
If 64GB is enough, the larger size is not recommended, as more capacity more challenge on SD card quality and compatibility with Dashcam.
Sandisk is a very reliable card. I use Sandisk exclusively. never had any issues with the card in over 4 dash cams i have used.
Amazon has a great returns policy, so if you have access to Amazon in your country, i would recommend to purchase there. worse case, you get a faulty card (unlikely if you get a card that fulfilled by amazon!), you can return with no issues.
