What type of object will the Sun leave behind once it finished dying?

I know the answer is white dwarf, but what will its mass be like? big or small?

What types of objects will high-mass stars leave behind once they finish dying?

I want to say neutron stars, but what size, mass, and luminosity will they be?

If astronomers could detect and count up all of these types of objects what type would be the most numerous and why?
