Opinions for a FTM ...how important/helpful/necessary are birthing classes?

Ruah • Finally preggers with my rainbow baby🚼 baby dust to all you ladies!!!
Is this something that's really going to help? I'm due November 20... I signed up for a breastfeeding class because I really want to breastfeed but I have not signed up for a birthing class yet I was just wondering from you ladies who took them or didn't take them did you regret it or find it helpful? Most of my friends said they felt silly and only went one time
