This is not in your list but I voted of for cpu ,proof of capacity is a good mining option it is asic free and any one can mine this coin,Burst is the only coin so far that is implementing this algorithm,they have a fast growing community and volume and price is spiking up,why not add this to one of your option.
I agree with you. Proof of capacity is great mining option. Look at the prices of storage in last few years. In next 5 years I expect that proof of capacity mining will be more popular due to storage price constantly decreasing
