Fujinon 105/5.6 W should not cost you much and should cover the format with little movements. The 90 mm lenses are mostly not cheap. There are also Fujinon 125/5.6 and 135/5.6 lenses. I have the latest version of the 125 (the CM-W) and it is a stellar lens.
For the long focal length consider G-Clarons (240, 270, 300) or Fujinon 250/6.3 (or 250/6.7) - the latter has more coverage but for 4x5 that is not relevant. There are compact and light lenses like Fujinon A 240/9, Nikkor 300/9, Fujinon C 300/8.5, but these are not cheap. Some Commercial Ektar could do the job too (those should be excellent lenses).
Should a bit shorter be enough that the plasmats (Nikkor, Schneider, Fujinon, Rodenstock,) are of acceptable size at 210/5.6. Above that the size and weight explodes.
In general - if you are a beginner - do not bind yourself to focal length you just covered from small format (BTW a more correct conversion factor would be 3.2). Keep in mind that you will probably shoot different subjects that you do with 35mm (at least partially)
I would strongly suggest you to get something like 125/5.6 or 135/5.6 lens - this will give you more space for movements and accomplis it a 210 or 240 (or thereabouts) lens. 270 may be a bit too long for your camera - both for bellows and weight.
125/210 were lenses I used for a long time. There is 210/6.3 Caltar which is actually Rodenstock Geronar E and it is a very nice, small and cheap lens (I used to have one until I got Fujinon A 240/9). You should be able to find one for about $200. Advantage is - it is a rather recent lens and it comes in modern Copal shutter and the chance that the shutter will need a CLA is small.
Little hint for the Fujinon W lenses. There are two different models - the older ones have lettering inside the lens filter (you see them when you look at the lens from the front such tat you see the glass) and the newer have the lettering from outside the lens barrel. The older ones have larger coverage by a few degrees. Both offer very good performance.
All Caltar II-N lenses are Rodenstock Apo Sironar N - very good perfomers for reasonable price.
Good luck and be sure to check out the
