Maybe you could try https://github.com/charlespascoe/vim-go-syntax. This might provide an improved syntax highlighting for GO.
There are plugins to do semantic highlighting. I don't use any of them because I'm satisfied with Vim's native syntax highlighting and with tree-sitter (and also because I don't use LSPs), but searching for "Vim semantic highlighting" on DuckDuckGo yields this: https://github.com/ycm-core/YouCompleteMe. The highlighting used in its demo is too baroque for my taste, but looking at your VSCode screenshot, it looks like it would be right up your alley.
You need to configure a language server. For C++ it's a bit tricky, so good luck with Go. There are other plugins that provide semantic highlighting using LSP, for example https://github.com/prabirshrestha/vim-lsp (I didn't try it, but it seems good).
