Nobody told me that the DOHC CBF Hondas are this or that, I am talking from experience, ( it is my daily ridder )not because I own a CB750F. The CBF's ( 750, 900 and 1100 ) also have the added advantage of having what was then ( at time of production ) and
still is excelent braking power. The front and rear calipers ( front and rear disc brakes ) comefited with dual pistons. The braking power is excelent, and with your big frame, that is something to consider. I also had Kawasakies ( GPZ 550, 750 ) Yamaha Secas ( 550 , 750 ) and for a short time a Suzuki GS1100E.
I did not keep the 550's for long because I did not like how light those were, and how small. Judging from your weight and height, I recomend a Honda CB900F or CB1100F. I own one and I can attest to their power , reliability and swiftness. I would recommned any big bike for you, the Suzuki 1100E ( the one with the large round headlam, 1983) is a great bike too.
The 83 ( not 84, the model changed) Kawasaki GPZ 1100 is one bike that I always wanted, and still look for one. That is a nice powerfull bike.
You are a big guy, a 550 will not be the right bike for you. I am giving you my honest advise. My CB750F is great, I think size wise is a good choice for you, but I would go up in power, the 1100 or the 900 are basically the same bike, with bigger cc's.
Good luck, I hope you end up with the bike you like, with the power to move you around , brake power, etc to give you a great time.
