1. Deciding the Right Approach

Choosing the right framework and backend for your e-commerce app depends on several factors including your team's expertise, project requirements, and long-term maintainability. Below are the pros and cons of each option you mentioned:
Option 1: React Native with Vue Storefront

Pros:

    Cross-Platform: One codebase for both Android and iOS.
    Vue Storefront: Provides a headless PWA front-end with integrations for various e-commerce back ends (Magento, Shopify, etc.).
    Community Support: Both React Native and Vue Storefront have strong communities.

Cons:

    Learning Curve: Your team needs to be proficient in both React Native and Vue.js.
    Complexity: Setting up and maintaining a headless e-commerce solution can be complex.

Option 2: Woo Commerce App

Pros:

    Ecosystem: Woo Commerce is well-integrated with WordPress, making it easy to manage the store and content.
    Plugins: Large number of plugins and themes available.
    Cost: Generally lower development cost compared to custom solutions.

Cons:

    Performance: Native Woo Commerce apps might not perform as well as fully native or headless solutions.
    Flexibility: Less flexibility in customization compared to headless setups.

Option 3: Android + iOS Native with a Custom Shopping Cart

Pros:

    Performance: Best performance as it's built specifically for each platform.
    Flexibility: Maximum flexibility for implementing custom features and integrations.
    User Experience: Potentially the best user experience with platform-specific UI/UX.

Cons:

    Cost: Higher development cost and time due to maintaining separate code bases.
    Maintenance: Requires more effort to maintain and update both Android and iOS versions.

Option 4: React Native with Headless Drupal

Pros:

    Flexibility: Drupal is a powerful CMS with robust content management capabilities.
    Cross-Platform: Single codebase for both Android and iOS.
    Experience: If you already have experience with Drupal, leveraging its headless capabilities can be advantageous.

Cons:

    Complexity: Managing a headless CMS with React Native can be complex and requires good knowledge of both systems.
    Setup Time: Initial setup might be longer compared to other solutions.

Recommendation:

React Native with Vue Storefront or Headless Drupal can be great choices if you want a flexible, scalable solution and are comfortable with the complexities of a headless setup. If ease of setup and lower cost are priorities, WooCommerce is a good option, though it may not offer the same level of customization and performance.
2. Integrating a Graphics-Heavy SDK

For high-performance graphics manipulation, using native components can be crucial. Here are the approaches:

React Native:

    React Native Modules: Write native modules in Java (for Android) and Swift/Objective-C (for iOS) for graphics-heavy operations. This allows you to leverage native performance while keeping the majority of your codebase in JavaScript.
    Libraries: Use libraries like react-native-svg for vector graphics or react-native-reanimated for complex animations.

Native Development:

    Android: Use frameworks like OpenGL or Vulkan for graphics-heavy tasks.
    iOS: Use Metal for high-performance graphics rendering.

Conclusion

    For flexibility and future scalability, go with React Native with a headless backend (Vue Storefront or Drupal).
    For simplicity and lower costs, choose WooCommerce.
    For maximum performance and customization, develop separate native apps.

For integrating a graphics-heavy SDK, leveraging React Native with custom native modules is a balanced approach, offering both performance and maintainability.
