Boost WordPress Site Speed

My WordPress site feels sluggish and I’m focused on one clear goal—sharply cutting the page-load time so visitors never have to wait. I haven’t installed any caching, CDN, or other performance plugins yet, so you’ll be starting with a clean slate and can choose the stack that best fits the job (e.g., WP Rocket, W3 Total Cache, Cloudflare, image-compression tools).

Here’s what success looks like to me:
• First Contentful Paint and Largest Contentful Paint comfortably inside Google’s “green” thresholds on both mobile and desktop.
• Repeat views benefit from efficient browser/server caching.
• Any solution you deploy remains compatible with my current theme and plugins without breaking layout or functionality.

I’m open to additional tweaks—server response tuning, image optimization, or anything else you feel will shave off extra milliseconds—as long as the primary focus stays on faster page loads. Please outline the exact steps you plan to take, the tools you recommend, and a rough timeline to hit these metrics.
