In my experience, Go is really great for writing web backends and CLI tools. Go has replaced Python for me for those use cases and I know it has for others too. I think they've thoughtfully evolved the language (generics took several iterations before being accepted). The tooling especially (cross-compilation, golangci-lint, GoReleaser, the VS Code plugin) makes writing and distributing my little Go apps a blast. Much easier than Python/C++ (though I must say the recent pyproject.toml stuff is really helping me package Python when I need to).
