I also use lsp-mode+clangd and it works very well. I get completion, jump to definition/implementation/usage, type hints, inline docs, fix-it hints and some minor refactoring help. I do get some random emacs hangs from time to time (I assume it blocks waiting for some clangd output), likely due to an interaction between lsp-format-region and aggressive-indent-mode. It is an explicitly unsupported combination and it is resolved by killing clangd but it is a bit annoying. I should try eglot at some point.
