Shimano disc brake pads: recommendations

I have 5800-series Shimano disc brakes on my road bikes and my pads don’t have much meat on them anymore. So I had a quick peek at Shimano’s website (for the R7000-series, but I figure they the pads are compatible) and they offer no less than 5. I know the difference between resin and metal pads, but it seems there are 5 different resin pads and 2 kinds of metal pads. What’s the difference between them? (Currently, I have L02A resin pads on my road bike.)
