My first "real" surfboard - novice girl surfer

Hi there!
I'm a long-time lurker, first-time poster. I'm looking for advice on an upgrade from my 8' foamie.
My "dimensions" are: Height = 5’ 3’’ (160cm); Weight = 110.2 pounds (50kg), late 20s, pretty fit (daily gymming and boot camp).
I've been surfing for 1.5 years (still very much a novice), mostly on weekends, but in the last two months, on a daily basis. My current log is a 8' foamie and during this time, I've used it to catch broken waves initially, and have now progressed onto green waves. I usually surf 1-3ft conditions, beach breaks in Australia (Dee Why, Manly, northern beaches etc). I can catch green waves (although I still miss plenty) and I'm starting to angle and veer, although I can't seem to turn. My paddling power has really improved since my daily surfs, and I can out-paddle quite a few fellow novices when getting to the lineup (yippee!).
According to the pinned guide on this board, I should be getting a 6’8" funboard (is that the same thing as a mini mal?), 20” width and 2 4/8” thick. However, I've been told by guys in the surf store to get a 7'6" / 7'8" mini mal at a minimum. To make matters more complicated, my friend, who is similar in weight, height and surf experience to me was recommended (and has since bought) 6'8" x 20 5/8 x2 3/4 mini mal. She is yet to try it out.
I'm thoroughly confused on what dimension board to get. I have also surfed a 6'8 x 20 1/2 x 2 3/4 Ripcurl Joystick (only for a day). I was able to paddle out on it and I caught probably the biggest wave I have ever ridden (maybe 4ft?), but I did feel pretty unstable on it whilst in the water.
Any advice would be gratefully received! Thanks!!!
