My understanding IFR is completely (or mostly?) without GPS, and uses plane-based instruments for direction, heading, speed, altitude, anything else? And like ground-based radio objects, such as localizers, I don’t know the terms or if there are multiple systems?
Can you dumb that down a tad for me?

Highly depends on the approach. IFR can be a lot of stuff. All systems can be used at once as well (And in many cases, they are used all together)
