Best way to connect hose spigot to PVC pipes?

Not sure if this is the right place for this question because this is more of a question about irrigation for garden beds as opposed to lawns…

But what is the best way to connect a 3/4” hose spigot to PVC pipes (varying diameters)?

My garden beds have PVC pipes ran all throughout that originally had a different irrigation setup, but some recent renovations/hardscaping renovations altered the water source. The pipes themselves still work, and I just need to get water to them. I have a hose spigot not far away and was thinking about just connecting a hose to them (manually changing where it connects, as needed).

I figured this would be a simple thing to figure out, but I’m seeing results that don’t seem relevant or applicable.
