Plants that can't tolerate soggy/mucky soils are often misinterpreted as preferring to be potbound, especially by those prone to overwatering. That means most potted plants, for which the retention of excess water is the primary difference between a plants' natural environment and its' pot. If you alleviate that condition, any size pot will be fine. Within reason, the sooner a pot dries, the better, moisture can be restored to an even level from top to bottom. Not everyone has the time to water plants every few days, so it's a balance each plant-o-phile must find. As a recovering serial overwaterer, I love having soils that drain quickly enough that my usual decision when I'm unsure (just a little sip for now) which is probably usually wrong, can do no harm.
