I use emacs as an IDE with a large C++ (and python) codebase. I use emacs-lsp + clangd for completion/jump to definition/syntax error highlighting etc, but for whole tree searches, I find clangd unreliable, so sometimes I fall back to emacs-ag (I assume that emacs-ripgrep would be even better) for brute force searches. I never found a side panel of any use (many are available), but I use projectile for quick jump to file all the time. My python setup is less refined than C++ (I haven't bothered yet to enable LSP), but I use elpy which is works fine for lisp-style programming with a persistent REPL.
