You should try again and reconsider if your team truly doesn't have an answer.

Most everyone using React should be using Nextjs or similar level of frameworks. Server rendering comes out of the box. On the other hand, it really isn't too complex anymore. With Next, Sveltekit, Remix, Nuxt, and friends, you get simple, hardened tooling out of the box. And you've decoupled frontend from api which many teams find very helpful to split responsibilities and allow certain features to move at different paces.
