LCSC parts for Coil & Capacitor
I've taken the liberty of screenshotting the relevant parts of your schematic.

L1 and L2, which use this symbol:



are, I believe, ferrite beads, for filtering. The double bar represents a magnetic core; here, a solid bar is used, which is supposed to indicate the use of electrical steel (a dashed bar indicates ferrite) but many people who draw schematics don't reliably distinguish between these; it's likely this is a ferrite bead.

The capacitor symbols you mention, which appear like so:



I can only interpret as polarized capacitors. However, looking at your image of the board, they are populated with what looks like MLCCs, a non-polar type of capacitor. This indicates to me that the schematic is a few years older than the board, as 10μF used to be a lot to ask of a ceramic capacitor and designers would be more likely to use aluminum or tantalum electrolytics. Today, 10μF MLCCs are common enough that they've replaced electrolytics in many applications.

Note: I am not claiming to be an authoritative source on this. Take what I say with a grain of salt; this is just an engineer talking from experience reading schematics that sometimes include unusual symbols.
