I started with a Naish Hover 6'5" by 31" with 125ltrs. I'm 85kg. No foiling experience, but am (was! ) a competent kitesurfer and SUP surfer. I found the Naish 125 a great board to start with, and I didn't ever feel like it held me back, in fact for downwind foiling it's still perfectly acceptable for me. I'm upgrading to a shorter board (5'9 by 29") with a bit less volume (approx 110 ltrs) simply because the time is right for me. The only other board I've used is an f-one SUP foil board 6'5 by 26" with 95 ltrs and it was WAY too unstable for me at the time. I've always preferred a wider board, partly that's just me but also because its nearly always choppy where I am - if your local spot is glassy smooth I expect you could get away with less width. Sea conditions are just as important when selecting kit as rider skill level and style of riding (ie wave riding, downwinding, wind wings etc).
Personally I think if you've got the money to spend then its always going to be best to get a beginner board to start with and then sell it and upgrade to a smaller board when you're ready. That way you'll have a much better chance of working out what board style you prefer. If you get a smaller board to begin with it'll save you money (if you get it right the first time!) but it'll make the learning curve harder and therefore longer.
All the boards you've listed are fine, I'd advise discounting those above 7ft simply because the extra length doesn't seem to provide many benefits over those from mid 6ft to 7ft.
