As you now know SBO is a source of lots of opinion and knowledge.

Great that you are keen to learn!
I’m curious what actual on the water experience you have? Are you a strong swimmer, outdoors oriented, comfortable being in or on the water etc. ?
I ask as I have taken lots of people who expressed an interest in trying a GENTLE < 10 knots sail where I kept the heeling to an absolute minimum. I would place them in three groups,
1) Really enjoyed it and went on to get their own boat
2) Comfortable but didn’t ask for another turn going out.
3) Very uncomfortable to the point that I dropped the sails and motored back.
They all started from the same place but left with different “impressions” of the sailing experience.
