one would prefer to connect with my gear for a beginner. I am just not sure on the harness to connect in the front, seems smarter to me, but it appears it connects to the back
U r right, it is built to connect on back, but there is room on the right or left front on the spreader bar if you push a bit of the fabric out of the way. u are right it is smarter to connect on the front.
As to why harness builders keep putting the attachments on the back . . . . because it looks cooler because you are all "wakestyle" or something? I dunno.
In wakestyle you have your harness connected to a slider on the back so the connection point can slide to the right or left supposed to help you for doing handle passes.
