why don't you use a servlet instead of a model. Here is the sample below:

<form action="/bin/processFormData" method="POST" accept-charset="UTF-8">
    <input type="checkbox" name="category" id="category-about" value="about" />
    <label for="category-about">ABOUT</label>

    <input type="checkbox" name="category" id="category-innovation" value="innovation"/>
    <label for="category-innovation">INNOVATION</label>

    <input type="checkbox" name="category" id="category-investors" value="investors"/>
    <label for="category-investors">INVESTORS</label>

    <input type="checkbox" name="category" id="category-news" value="news"/>
    <label for="category-news">NEWS</label>

    <input type="checkbox" name="category" id="category-sustainability" value="sustainability"/>
    <label for="category-sustainability">SUSTAINABILITY</label>

    <div>
        <input type="submit" value="Submit" class="form-submit">
    </div>
</form>

The servlet to handle post:

package com.yourpackage.servlets;

import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.osgi.service.component.annotations.Component;

import javax.servlet.Servlet;
import javax.servlet.ServletException;
import java.io.IOException;
import java.util.Arrays;

@Component(
        service = { Servlet.class },
        property = {
                "sling.servlet.methods=POST",
                "sling.servlet.paths=/bin/processFormData"
        }
)
public class FormDataProcessorServlet extends SlingAllMethodsServlet {

    @Override
    protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
        String[] categories = request.getParameterValues("category");

        if (categories != null && categories.length > 0) {
            // Process each selected category
            Arrays.stream(categories).forEach(category -> {
                // Perform actions based on the selected category
                // For example:
                switch (category) {
                    case "about":
                        // Process 'about' category
                        break;
                    case "innovation":
                        // Process 'innovation' category
                        break;
                    case "investors":
                        // Process 'investors' category
                        break;
                    case "news":
                        // Process 'news' category
                        break;
                    case "sustainability":
                        // Process 'sustainability' category
                        break;
                    default:
                        // Handle other cases if necessary
                        break;
                }
            });
        }

        // You can redirect to a different page after processing the form data
        // response.sendRedirect("/your/thank-you-page.html");

        // Or you can simply set a response message
        response.getWriter().write("Form data processed successfully!");
    }
}

See if this one makes sense.
