ha-ha, brother, I feel you. Infra engineer (VP last position) and built an app with Refine. I was exactly in your position not a long time ago. I tried to choose "The Best Framework Ever" and made a lot of mistakes, and at the end, if you don't know frontend go with the flow: React + Next.js. Not because they are Best Ever, but because the majority of content online is dedicated to these frameworks. StackOverflow, ChatGPT, a friend who speaks frontend, etc.
I did some work as part of my consultancy, had data left and decided to try my hands at frontend. Oh, boy, I think it was a mistake, but it was a lot of fun, will do again. https://cloudprice.io
