Amazon CloudFront is the appropriate service for efficiently caching and delivering web content to users with minimized load times because it is a content delivery network (CDN) that stores copies of content at edge locations closer to users worldwide. This proximity reduces latency and improves data transfer speeds, enhancing the user experience. The incorrect options provided do serve other specific purposes, such as improving application performance across regions (Global Accelerator), establishing dedicated network connections (Direct Connect), and offering managed file storage (Elastic File System), but they do not focus on caching and delivering web content globally like CloudFront does.
