Quite a high end board, so should be fine.
All of the above and more.
There are some electrolytic caps for the audio chipset, this is relatively normal as they have better characteristics for that work. Little silver topped yellow wrapped ones in the bottom left.
Most common large capacitors found in computer electronics these days are surface mount aluminum electrolytic capacitors. These are the ones you see around power electronics.
Polymer aluminum caps are also commonly used in some power delivery. Often referred incorrectly as POSCAPs, these are thin black rectangles. Often see these on PCBs where height is limited.
And the most common capacitor on electronics will be tantalum. These are little yellow rectangle/cubes that you find around all kinds of circuits.
