Usually PHP. I grab Laravel, Tailwind CSS, Vue and the needed libraries like VueRouter, Vuex and a few PHP libs and see what happens.

The correct answer is mostly what others have said: whatever you know best. But I would caveat that with this: if this is a project just for fun and learning, pick anything you want and the most important part is have fun. If you are trying to do RAD and get something in a market, grab what you know best and go from there.
