GNU/Emacs go-mode VS gofumpt

It seems that most Go utilities have been submerged into gopls, the LSP server. So a lot of older websites that suggest how to configure go-mode might be outdated, because of the cultural shift away from the unix-ish little, collaborative utilities approach. This means you will need a LSP client -- the Go project has some documentation on that. I'd strongly recommend Eglot, if you are uncertain what to use(0). This page explains how to install gopls with your Go toolchain.

I haven't used Dash, so I don't know the specifics of what it works, but if it works like running pydoc or godoc or whatever Java has inside your text editor, here is a plugin for pydoc inside emacs and here's another for godoc (as part of a larger mode for go). I just tested godoc and it seems to work fine, if a little too basic.

This question makes very little sense to be honest. Try using spacemacs. It has a go language server runner. Otherwise try this https://github.com/dominikh/go-mode.el

In the roadmap section[1] the author says it's more of an experiment with a possibility that some of the rules might end up in the original 'gofmt' tool. While I agree that Go having a de facto formatter built in is wonderful, there are some absolutely fantastic additions in 'gofumpt' that I do hope wind up in 'gofmt'

No. If you want more strict formatting, you can use https://github.com/mvdan/gofumpt. Apart from using that, there is literally no reason not to use it.

I am the author of go-global-update, the missing command to update globally installed go executables (like gofumpt, gopls, gotop, and other CLI tools you may have installed globally in your system - in your GOBIN directory).

I think that the one tool that might still be useful outside of gopls is goimports. It can be used as a gofmt replacement, that also automatically manages and removes imports. Gopls can integrate staticcheck and gofumpt, but my understanding is that they have to be installed manually. See the settings section for more on that(1).

I use gofumpt but I'm pretty sure it doesn't wrap either (and I don't want it to so we're good)
