Maybe I am assuming to much from your post, I apologize if I am.
I would suggest first getting more experience sailing, and discover what aspects of sailing you are seeking, and the best fit of boat to desired lifestyle.
Join a club, take sailing lessons, charter boats...
Look at propulsion systems as an optimal solution to fit your and the boats needs.
If I have put my "ass" before "u" and "me", please don't take in personally.
