Hey Enes! I think that mainly depends on which kind of POC you want to build. Should it be mainly client-side, a SPA? Then you'd probably want to add some state management on the client-side (like Redux), and probably a library to help with the communication, too (like Apollo). If it's doable or desired to generate as much as possible on the server, you could have a look at Remix, they have some really nice architectural choices that would align with your other decisions quite well I think!
