We open the windows as often as we can. If the humidity is under 60-65% and the temperature is under 82-85, our house is comfortable though those upper humidity/temperature numbers are pushing "comfortable." Right now, we have had the house opened up for getting close to a month. I actually closed the windows last night because the house was getting too cold. If the outside temperatures are cool enough we will leave the windows open at night to cool down the house. This works well as long as the night gets cool enough. Last night before 10:00pm, the temp was in the mid 60's with the humidity being a bit higher. We have not had a problem with mold. Mold requires two things to grow, food and moisture. If one of those is gone, mold cannot grow. Our house does not stay with high humidity for long so we don't have mold problems.
Pollen can be a problem. Some spring days we close up the house because of pollen. We are not allergic to pollen but pollen can really dust up the house. Pollen problems for us is related to rain. If it rains frequently, the pollen is not so bad, but if the rain is infrequent it can get nasty.
Not every day is high humidity or high pollen. Even during the summer we have low humidity days. Not often but it happens.
One of the house's we looked at was supposedly energy efficient. The houses were built from 6x6 PT timbers for external and internal walls. The houses had an internal envelope that allowed air to move from the lower to upper levels in the house. This was a real good design except for humidity. The house might be "cool" but the humidity would be unbearable in the South. The house was not designed to use AC.
I talked to people who had built the houses and then ended up putting in AC after a few years of high humidity. We did not build the houses because they made no money sense because of the required 2-3 levels and the envelope walls. The house may have been cheap energy wise but it was very expensive to build. The other problem with this house model was that they were using PT wood that was CCA and they owners were going to have problems selling a house that was full of exposed CCA wood.
