Advanced Fuuin is basically regular fuuin with the ability to submit S rank fuuinjutsu, use body seals, and also utilize the more esoteric variety of fuuinjutsu. Basic Fuuinjutsu for the most part utilized barriers and that was its primary focus. Adv. Fuuin however also deals with absorbing(sealing), releasing, etc.
It also allows one to use more chakra for their sealing jutsu, with Adv. Fuuin it allows your S rank techniques in this field to contain 60 chakra as a standard which is a major boon for sealing jutsu which operate on a chakra v chakra basis.
Regardless of the application of a seal, should a technique have more chakra it can overcome the limitations or point of a sealing jutsu if that technique targets the seal/barrier etc

Fuuinjutsu has several parts, barriers are key. There's the vessel (what is being seal into); the trigger (what triggers the process); binding (the seal itself); the chakra (that binds it all together); and the key (that can be used to seal/unseal). Once you got the process down, Fuuinjutsu becomes even more multifaceted. It is, after all, the first jutsu we see in the Naruto canon.

They need this advanced chakra control as the chakra is often used as a medium for checking the body of ailments, helping fix the body, and if necessary, damaging and removing the finer mechanisms that make the body work (Such as when Kabuto rearranged the nerve signals for Tsunade)
