Choose an ecommerce platform from the catalogue you have, the way orders are fulfilled, and the person who will add products on a Tuesday. Those three constrain the decision more than a feature matrix does.
A small, stable catalogue with straightforward shipping can live on a well-run hosted shop. Customer-specific prices, complex kits, or a B2B approval step push you toward a platform that can hold rules without a plugin pile. Moving platform because a pitch deck prefers a different logo is an expensive way to pause sales.
If you migrate, take the redirects with you. The products are not the only asset. The URLs that already rank are part of the shop. We scope that work on the ecommerce development page.
