The majority of my experience No limit holdem is no limit holdem mtt. Thus I'm not well versed in cash game starting ranges and I cant recommend this nor that. However, the principle of establishing a strong opening range that varies in composition depending on the number of opponents as the singular most important factor will always be the driving force in range construction no matter the format.
Look at the shapes of the ranges. The arrow points to AA, and there's a few more suited hands than offsuit. This is true for any default readless preflop strategy.
"raise sizing"
First you pick a raise size that best suits your tendencies and your opposition. Then you decide the range that yields the most ev with that size.
