I would like to install a small sub-panel in my basement. It will be approximately 55-60 feet from the main panel.

I will be running a fridge, some fluorescent lights, and occasionally some small appliances (meat grinder, deli slicer, etc.)

I was thinking a 30 Amp breaker off the main 200 Amp box and running four #8 wires in a 1" PVC conduit. (2 hot 1 neutral 1 ground.) Am I OK with the #8 wires, or do I have to go to #6?

For a 30A breaker, honestly, you're fine at #10 wire. At that distance you don't need a wire size bump even for 120V loads.

You said the word "cable" which means several individual wires in a sheath. That's not what you want, it's very difficult to pull through a conduit. Get individual wires, of type THHN (typically dual-labeled THWN-2). They will easily fit in 1" conduit.
