Realistically - you're a tall rider, several standard deviations away from "average" And that's a difficult place to find gear that fits.
Simply raising the saddle and lengthening stems doesn't do the whole job, because the bike's wheelbase doesn't increase as much.
Shorter riders can sometimes compromise using kids bikes, (which isn't meant in a bad way) whereas us taller people have fewer options.
I'm 195cm tall total, and my preferred BB-to-saddletop is 840mm.
I have a variety of frames, but the best fitting ones are around 58cm. If I could find affordable frames in 60-66 cm I'd buy to compare.
You might have to consider a custom made frame to fit your parameters, and they are significantly expensive.
Check out Conor Dunne's bikes, at 6 foot 9 inches / 206 cm he's a long lad.
That's an enormously long seatpost on a tall frame, and notice the long head tube too. As such he presents a lot of frontal area and gets less benefit from the draught, but provides a lot of shelter for anyone behind him.

Upshot - tall people bikes make seated-climbing harder because once the grade exceeds 3-5% then weight on the saddle is subtracting from your front wheel weight, leading to skittish handling and lack of control. A good power stroke on a steep climb will wheelie easily for a tall rider with a long seat post, so you're out of the saddle sooner/longer than an average rider, and short riders can stay seated for almost all climbs.
Solution - look for a frame with longer chainstays, to help keep the weight forward. This gives a frame with a longer wheelbase and better climbing/straight line stability at the cost of less nimble manoevering. IE a race bike tends to be twitchy, and a longer wheelbase calms it down somewhat.
