I don't no what board to get

Hi I'm pretty confused about what surfboard to get. I'm 13 years old I'm 5'4'' male and have an average fitness level. I am looking for a beginner board that will last me a while before I have to progress to a different board. I was looking at the 6'7" bic shortboard(see below) but am unsure if it will be too small for me. The dms for that are 6ft 7 x 20.75 x 2.4 and it has 38 litres of volume.

Please help me
