Terribly confused beginner looking for board

Hi guys,
I took my first surf lessons last year in Portugal and totally fell in love with the sport. I've recently had my second surf week and my plan is to go on surf trips for at least 6 weeks per year in the future.
So far I've had 10 lessons, did well in white water, not so well in green water. My excuse is that the waves were not very beginner friendly with a (according to surf-forecast) height of 1.5m+ meters and an energy that hammers you far back to the beach if you are not good at turtlerolling yet.
So, back to the title of my post: I would like to buy my own first board to be independent of surf schools and surf rentals. It's not that I don't want to take lessons from time to time anymore, but I would like to go into water whenever I want and try for myself.
What got me confused are the extremely mixed recommendations for a first board. For my data (5'9/181cm and 71kg) and level the surf channel videos, volume calculators and people on this forum recommend something between 7'0 and 40l to 9'0 and 60+l.
Summarizing it all I came to the impression that a 7'6 hard board with about 50l should be a decent board to improve on. More specifically, I'm looking into the Torq Mini Malibus of that size. What do you think?
Cheers
Michael
