Just a note on conky - it is more a language for building displays than an app. I suggest looking through the conky thread on here to see some of the possibilities - and perhaps to see the scripts that produced them before deciding to jump in!
If you do go for it, borrowing from existing is highly recommended! And, help is available here too.
You may also want to try conky-manager from AUR. It is a lazy way of having some ready-made pre-configured conky themes. I’m giving you an idea, here & ignore the fact thay’s applied on KDE plasma.
