TeXStudio if you want something that is easy to set up. VSCode + LaTeX Workshop if you need features from VSCode (other extensions, git integration,…).
Note that you still have to bring your own LaTeX installation (I always use TeXLive, but there are other options)
For literature I’ve found Zotero + BetterBibTeX plugin very nice, otherwise JabRef also exists but is much more “raw”.
