A full functional workstation that's generous to my eyes:

• coreutils/busybox/command line tools
• tmux (terminal multiplexer
• vim (editor)
• mutt (email client)
• lynx (web browser)
• profanity (xmpp client)
• weechat (irc client)
• gsocial-cli (gnusocial client)
• rtv (reddit)
• cliaspora (diaspora)
• madonctl (mastodon)
• newsbeuter (rss feeder)

Just to name a few, all running over #tty with no graphical server installed, #noxorg #nowayland #nonothing /to !shell !cli !nodesktop !sysadmin #sysadmin #nodesktop
