They're generally best ignored unless you have a specific reason to use them.
In my recently replaced board they weren't even usable because their PCIe lanes were allocated elsewhere.

Sound cards and SATA/USB controller cards can use them.
In case of PCIe v4.0 x1 slot would actually have bandwidth for quite a lot, but only X570 boards have it.
Previous AM4 boards use dozen years old PCIe v2.0 with only 500MB/s of bandwidth, which can be saturated by single SATA SSD.
For mechanical drives that would be quite good for two channels SATA controller.

I have my sound card in one of mine.
There really isn't much use for them these days, a couple of network and sound cards use them but generally they aren't all that useful especially when they turn up on a fully featured board that has 4x 16x slots. The only time you ever really see them used well is for mining/distributed computing projects etc, for example I have a board that has only 13 1x slots and with the right magic has 13 graphics cards plugged into them.
