I noticed that wirings have different kinds wires inside the rubber coating. Does it make any difference in terms of transferring electricity or being solid or strands have its own purposes?

Think of stranded wires as long ponytail. while a solid copper conductor as a styrofoam float (for swimming assistance)
The stranded wire is a lot more flexible (like the ponytail). Solid wire is not so flexible (like the Styrofoam float go swimming assistance).
To the rest who believe it has no effect on current carrying capacity:
there is a difference between current carrying capacity for stranded cable and solid cables for AC current. For DC not at all.
Alternating current travels via the skin effect and is highly dependent on the available surface area. This isn’t a big deal at very low voltage is like 230 VAC / 110VAC. butbut at high-voltage (say 1kv and above) it has detrimental transmission effects by virtue of increase in resistance.
DC is volumetric in nature. And will do better in solid conductor va stranded conductor (at very high voltages)
