Do be wary of Beaver Builder. It is a (pricy) subscription. I wanted a carousel a year ago and ended up going with Beaver Builder after many happy years with GeneratePress only to discover that it was a yearly fee after I paid what I thought was a one-off… I am in the process of returning to GeneratePress! I haven’t found how to do a carousel (so, sorry, not helpful in that way; I just think you want to ponder just how MUCH you want that carousel), so am doing without it, for now. If the GP team build a carousel plug-in, I’d be keen!
