I am just a bit lighter than you and I have the 10'11" psh xwide ripper I think I could have got away with the 10'6" xwr. Its a great board, stable and surfs real well but I have only had a couple of sessions on it and I am just starting out supping but have a surfing background.
The naish 10' mana or even the 9'6" mana would be alright as well. I recently had a paddle on the 9' star board hero and that paddled alright and was stable so the whopper would be a good choice as well. The 10'6" coreban rocket is another that gets good reviews by BFB (big fat buggers) and was the board I was originally going to get except it was out of stock.
I also have a 10' by 29.5 wide board that I struggle on. The deck on this is just awash. I think keep the length around the 10' to 10'6" and width over 30" and volume up around 170 + litres (as a guide). There are a few boards around now that suit us BFB. Heaps of options
