One thought before you go through all the contortions and rigmarole of getting things investigated and then sorted out. Set up the seat height at close to its lowest position, and then ride the bike a bit, not even a long ride, just a short test. If you are rocking back and forth as you ride, in your hips and in an exaggerated motion, it is probably little chance of the bike fitting you. This is just a suggestion to see if all the various fitting methods will be worth the time and efforts they will require. Not really highly technical, or scinetific, but you can have some idea of whether or not you can comfortably ride this particular bike..

Oh, as said, "Welcome To BF" and to the C&V Forum in specific. Good choices on your part, along with the bicycle.
