I need to figure out where I'm going to draw the line between these guides and the concept documentation pages.

Looks good, just some small nits.

What's the benefit of this?

Of explaining it? --from isn't supposed to be used in uv tool install.

Could you add some clarity about difference between uvx --from and uvx --with?

I think they are in common in all ways except of --from is one-time usable and it declares entry points of which package should be gathered.

I can suggest to merge --with and --from into one argument (e.g. --from). By keeping it multiple-times usable it in cli, by default, main package should be inferred from first/last passed --from argument. Which also could be overridden by separate argument e.g. --main.
Examples:

# inferred first `--from` as main package, so `fastapi` executable would be available.
$ uvx --from fastapi-cli --from fastapi fastapi dev
