Add a board to the quiver

Hey there, I am looking for a new board but a bit lost on what I need.
I'll give you some info:
I live in Italy, so the swells are not super clean and to surf you need long paddle-outs and many duck dives, to reach a somewhat clean zone;
I've 17yrs snowboard experience, 2yrs surfskate/skateboarding 1 and half of not very regular surfing;
I live far from the sea (2hrs), but I plan to move closer to surf more;
I've only done one surf trip to canaries where I learnt;
I am 177 cm and weight 79kg, I have good muscle strength and generally fit;
After the 100Lt softie, I've used a bic mini mal 7.3'' to learn (46 LT) and I now can catch unbroken waves also 6ft high, however I tend to loose a lot of speed when turning and trying to learn to cut the wave (also with the swelltech surfskate): I feel that I cut 56 Liters too early and couldn't learn properly the turning technique that is rather different than both concrete and snow;
Also I can ride unbroken waves but with the conditions here, I often get so tired from paddling and duck diving that I get just 4 good waves and then I have to rest a long while.
I am looking at a wide fish about 6.8''-6.10'' (like this https://www.torq-surfboards.com/tec-bigboy-fish.html) that gives me some more volume and stability when paddling, but at the same time should allow tighter turns than the bic.
Do you have any suggestion? Is my reading on what I need correct?
[Shall be moved in surfboard advice I guess.. sorry
