Hmm. Landscape, architecture, found objects.
With all due respect to more accomplished LF photographers, OP, what you really need for the subjects you have in mind is front rise and, ideally, rear fall. These movements are used to move the horizon up and down, usually to lower it to eliminate empty foreground. They'e also used avoid tilting the camera to include the tops of, e.g., buildings. Tilting the camera makes vertical lines converge.
And you want to use wide angle lenses, perhaps as wide as 58 mm.
As has already been pointed out, a monorail will do everything you think you want. Failing that, a field/technical camera that has a drop bed and that will allow easy focusing when the front standard is on the inner bed rails.
An inexpensive alternative that will get you started is the humble 4x5 Crown Graphic. Not ideal, but very friendly to short lenses. Minimum flange-to-film distance is 52.4 mm, the bed drops and inner and outer bed rails are linked, making for easy focusing with very short lenses. I don't know how much front rise 4x5ers have, my 2x3ers have 19 mm. No bag bellows, no recessed board (but, then, not needed).
Since you've been on APUG, sorry, Photrio, for nearly 20 years, you might be aware of "the list." If you're not, please ask.
And now for the insulting part. This forum is infested with experienced photographers who are eager to help. Few of us know everything; most of us recommend what we use and like, can't recommend what we're not acquainted with. We all have biases that we have trouble seeing beyond. "The list" has info on more cameras and lenses than most of us have used. Consult it.
Thinking of biases, I'm biased against using very wide angle lenses for landscape work. Shoot a broad vista with a w/a lens and you'll get a frame full of foreground, often uninteresting. Before shelling out for an expensive ultrawide, try a relatively inexpensive shorter w/a, e.g., a 90/8.
