I think you may need to figure out a couple of things in your mind first. You will need to carry a light meter, unless you use the sunny 16 rule or have been shooting long enough and often enough that, within reason, you dont need a light meter.
Any 4x5 camera will do pretty much what you want to do, but sharp as anything pictures takes dedication, practice, practice and more practice. You will also need to carry a tripod that can hold the weight of your camera without too much flex, otherwise start getting down and using bean bags, which arent too bad an idea.
You may wish to think about a graflex back that holds 6 sheets of film, which is great, but that back takes slightly more room than 2 double dark slides (DDS) containing 4 sheets of film, so not too much advantage there. I have both of these, Graflex backs and DDS. Not absolutely necessary, but handy, is a changing bag, more space.
Now the biggest killer, dust. Dust and/or dirt can get into and onto film or the insides of the DDS. Not really a great idea, especially if you are not that flash at spotting prints, your call. But you really need to load your DDS at home in a really clean place and place them in zip-locked plastic stuff to keep dust out, both before and after shooting.
As far as cameras go, anything with enough movement for moderate manipulation should be adequate, unless you are doing buildings where you may require some serious movements. You should probably have a single lens with quite wide coverage, to allow you to shoot straight or ensure you can cover the film no matter how wild you movements are. Not a requirement, but nice to have.
Probably the biggest asset, is to have a lens that will enable the camera to fold up with the lens still attached, this is my definite requirement for backpacking my 4x5 wood field camera.
Almost any camera you can find to start you off in the direction of where you may ultimately end up, should be what you look for. You may get your permanent camera first go, but not likely unless you try a couple of different systems prior and know what you need.
I have more than a handful of 4x5 cameras, but the ones that fit your description are a wooden folder and a converted Polaroid. The wooden folder I have is a Shen Hao and it is kitted out for back packing with a Fujinon-W 1:63/150 lens. Im not saying this is the sharpest lens around, but all things considered its pretty much an all-rounder with more than enough sharpness, in fact it is almost a sleeper of a lens as many people dont think too much of them, until they use them. The Fujinon lens when reversed, allows you to fold the Shen Hao, thereby eliminating any back pack space.
My converted Polaroid camera is a Razzle, no longer available as the manufacturer passed away recently. Mine is equipped with the same Fujinon-W 1:63/150 lens, works a treat and I generally use it with a Graflex back for portraits. I have taken it in a back pack once. Too heavy and a bit ungainly to pack, so I dont back pack it. I know someone who does and it works very well for her.
Some food for thought.
