You can get product data by product id using below code snippets.

<?php

namespace MagemonkeysProductCollectionBlock;

class Product extends MagentoFrameworkViewElementTemplate
{
    /**
     * Constructor
     *
     * @param MagentoFrameworkViewElementTemplateContext  $context
     * @param array $data
     */
    public function __construct(
        MagentoFrameworkViewElementTemplateContext $context,
        MagentoCatalogApiProductRepositoryInterface $productRepository,
        array $data = []
    ) {
        $this->productRepository = $productRepository;
        parent::__construct($context, $data);
    }

    /**
    * Get Product by Id
    * @param int
    * @return MagentoCatalogModelProduct $product
    */
    public function getProduct($id)
    {
        return $this->productRepository->getById($id);
