Add- " so humidity control can suffer a bit" unless the air is flow is slowed enough to lower the coil temperature several degrees below the desired inside dew point. Slowing the air flow will remove more moisture while maintaining a higher suction capacity. The negative factor is that more moisture is needed to get the coil to drip to the drain and retained on the larger coil which will evaporate into the home at the end the cooling cycle. This affects the muli-speed a/cs in a big way. They lower cooling capacity will very large coils. 1-2 lbs. moisdture per ton are need on a coil to start draining. At the end of the cycle, the retained moisture evaporates back into the home. Make the cooling cycle are long as possible. Using a whole house dehumidifier for maintaining <50%RH during low/no cooling loads is much more effective.

Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
