React is not a good way to go if you want a beautiful lighthouse score. FCP score will always high because the way React works is based on loading a big chunk of JS. You can consider moving your app to NextJS if you want to improve your app FCP. LCP normally can be improved by reduce the size of images/videos, eliminate the things that block your loading and rendering. You can read the detail from here
