I'm wondering how you use clangd. Is this lsp-mode or eglot? I'm using
lsp-mode ATM, just because I tried it first, and it worked for me.

I've never had to use --force-wrapper or alter compile_commands.json.
My current version is bear 3.0.20, on macOS 12.6. What's your system?
P.S.
WRT to seamless, I have to add, for macOS: This was true for me with
Xcode 13, and is no longer with Xcode 14. Both clangd and lldb crash
pretty frequently :-(.
