Types of debate that are NOT focused on speed?

I am a sophomore who enjoys activities such as Model UN and mock trial. My speaking style is best suited to the type of activities.

Are there any types of debate where emphasis is placed on genuine public speaking ability, like in MUN and Mock trial, different from the “talk-as-fast-as-you-can” styles of debate like Policy and Lincoln Douglass?

I understand that Congressional Debate has the type of style that I am looking for. Are there any other debate types with a similar approach to debate, i.e. not so fast that most people can’t even understand what is happening?

Public forum and parliamentary debaters don’t spread. Those would probably be your best options!
