Others have mentioned the awesome projectile, but I think it should be said that Emacs now has built in project.el which has come in leaps and bounds (though probably still lacks some projectile features). I use project.el alongside consult[1] which has many convenient wrapper functions over built-in ones, like an enhanced `switch-to-buffer` with project support. I am actually using an even tighter integration called consult-project-extra[2]. The most advanced and overkill solution would probably be to use bufler.el[3] which basically allows you to define your custom logic for buffer grouping.
