Child theme for production site?

Hello, I am new to making websites, and not versed with coding. I am keen to build an WooCommerce site for selling our products (mineral specimens) using a block theme, and thought Wowmall sounded like a good starting point. You do not recommend Wowmall to be used for production sites, though, so I was wondering whether creating a child theme from Wowmall, and using that for my website, would be a good workaround? Will that allow updates to be installed without loosing any of my customizations? Or should I try a different theme? Thanks a lot in advance for your advise!
