I'm not consistent on 4x5
I'm not consistent on 4x5
I play with 4x5 but my experience is far from consistent on a one system solution.
My friend however seems to shoot what you are looking to shoot.
He uses and aged Tachihara, near 3 decades old. 3 lenses (the only time I have seen him buy a new lens is to get a nicer one of the three he uses which have always been near mint anyway), the same tripod and all his work on Fuji Velvia.
That said, what has he been able to do with a three + pound Tachihara, with the system, and film in a backpack, out in nature.

The man is singleminded in his work ethic and style. Same equipment for years I would vnture that every image on this site was visited many times each, different days, different times of the day, different lighting conditions.
Very purposeful and close to 30 years on the same Tachi as I recall.
I've had three Tachiharas. They're light and a bit fiddly but dependable. They have all the movements one needs for outdoor work. I've owned two Shen Hao;s. Real tanki folding camera... more like 6 plus pounds w/GG cover. Real overkill on movements for what you seem to want.
I think the Chamonix is very much like the Shen Hao, but a bit more refinement on the focus system... same weight.
I've thoroughly enjoyed my relationship with three Toyo 45CF's (Carbon Fiber) light and requires care when locking down. Gorilla hands can hurt the lock down bosses.
If you want to know Bruce's lens selection, ask me, and I will find out.
