For a standalone shop with the fewest moving parts, start with OpenCart. It is the only store on this list with a Docker path, it runs on plain PHP and MySQL, the directory estimates 256 MB of RAM, and it has been maintained since 2009 with about 8,200 stars. If you already run WordPress, the category's default advice still stands and WooCommerce is the better first store; it simply rates Medium, so it is not ranked here. Either way, "easy" in e-commerce describes the install, not the job of taking real money safely.
Half this list is not a shop

| Easy Digital Downloads | Plugin for selling digital files | WordPress | 512 MB |

| WooCommerce POS | In-person till for an existing WooCommerce shop | WooCommerce | 256 MB |
Alokai Storefront UI is code for developers, not a store. Easy Digital Downloads and WooCommerce POS are add-ons to WordPress setups. That leaves three real standalone stores, and OpenCart's community is many times larger than AbanteCart's or LiteCart's, each of which has a few hundred stars or fewer. With a payment flow at stake, a bigger pool of people who have hit your error before matters more than a smaller footprint.
What "easy" leaves you to do
TLS is not optional. Checkout is where card details or payment redirects happen, and no payment gateway will work with a store served over plain HTTP. Put the shop behind a reverse proxy with a certificate before you configure payments.
The admin panel needs hardening on day one. OpenCart's installer leaves an install/ directory to delete and an admin/ path that automated scanners probe constantly; rename it, set the new path in the admin config file, and make both config files read-only once the install finishes.
Persistence and backups cover two things: the MySQL database, which holds orders and customers, and the image/ directory, which holds product photos. Dump the database and archive the images nightly, and restore them into a test copy once before your first busy season.
Give each staff member their own admin login so you can see who changed a price.
Budget for extensions too. Payment gateways beyond the bundled set and most shipping integrations come from a marketplace where many are paid, and an extension built for OpenCart 3.x will not load on 4.x. Check that the gateway you need supports your version before you install.
How much RAM does a small self-hosted store need?
The directory's 256 MB for OpenCart covers PHP; MySQL needs its own share, and you want headroom for traffic spikes and the admin's reports. A 1 GB VPS runs a small catalogue, and 2 GB is the comfortable default once the database and backups share the box.
When to step up
If you need inventory across warehouses, more built-in features, or a theme marketplace deeper than OpenCart's, PrestaShop is the closest step up; the OpenCart vs PrestaShop comparison lays out the trade. If you are moving to WordPress anyway, WooCommerce brings the largest extension ecosystem. A catalogue heading past 10,000 products or a developer on staff points toward the platforms in the category's buyer's guide.
What I'd do
Install OpenCart 4.x on a 2 GB VPS behind a reverse proxy with TLS, delete the installer, rename the admin directory, and confirm your payment gateway's extension supports your exact version before you add a single product. Set up nightly database and image backups the same day. Choose WooCommerce instead only if a WordPress site already exists.
