Did you really want a rangefinder, I'm assuming the designated Focal Lengths are just the only available cams. The Wista 45RF should have more movements than a Super Graphic, and be OK with lenses from 75mm to 300mm..
I do shoot with two Speed Graphics, a pre Anniversary no movements except rise, but I only use it with barrel lenses anyway, and a Pacemaker Speed Graphic, I had a Crown Graphic as well but sold it. The downside to Pacemakers is poor movements. My main 5x4 camera has been a Wista 45DX plenty of movements.
Back around 2007/8 I bought a cheap Super Graphic, I often use it hand held, while movements are limited they are enough for landscape work. I don't use the rangefinder which need repair, but I can shoot very fast with it, compose on GG screen, maybe slight front tilt. Then close the shutter, stop down, insert the DDS film holder, remove dark-slide, use the wire frame finder to frame again, it's remarkably easy and quick, 10 seconds or less.
