Any other factors to consider? NOTE - I am aware I might simply use a 20mm and then tinker in photoshop to fix the converging lines in post. I am not interested in doing that because I want to see the corrected image as I compose, in the viewfinder, and then on the negative.

Anyhow - I was leaning towards the 28mm Nikkor when another factor came to mind - sharing it here in case someone else is going through the same sort of decision.
As stated I would like to test the possibility of using this lens mostly handheld. One risk might be that I'll find it difficult to properly align the vertical lines I'm seeing to the vertical.
Many thanks for your comments everyone. I picked up a sample of the Nikkor 28mm PC. Looks to be in great condition, impressed with the precision of the shift mechanism. It has a nice solid feel to it, looking forward to testing it with some film soon.
As an aside, it appears to be easy to focus on the F90X. The shift effect is easily visible within the viewfinder although at maximum shift it does seem to produce a kind of darkening/vignetting on the side of the frame close to the shift direction. Might be by design.
I might end up using this on an old FE body of mine - I almost forgot I had it and I never liked it so much, but it could be an ideal match for this lens, especially because it has interchangeable focusing screens and I might pick up an E series one with the grid pattern to go with it.

All you need to do is point the camera at the horizon: when the film plane is perfectly vertical then vertical lines will be rendered as vertical. If you can do this then you don't even need to use your eyes to check the verticals (unless you want to intentionally add some convergence or divergence).
The simplest tool to achieve this when shooting from a tripod is to pop a bubble level on the hot shoe (assuming the plane of the hot shoe is perpendicular to the film plane and the bubble level is accurate). But I guess that's not much help when shooting handheld as it'll be tricky to get a reading from it when looking through the viewfinder!
But the principle for handheld shooting is the same, however you achieve it: point the camera directly ahead first, don't point up or down, and then adjust vertical shift to bring the top of the building into frame.

your recommendations are counter to the use of a PC lens.
Is a PC lens different from a shift lens?
I am looking to purchase a specialised 'shift' small-format prime lens to use for amateur architectural film photography. I run 2 35mm systems, a Nikon one (my main body being an F90X or N90S as it is known in the US) and an Olympus one (centred around an OM2n). I use both kits equally and like them both about the same.
Is a PC lens different from a shift lens? In a shift lens, the image circle is greater than the format size. The shift function shifts the image circle up and down and/or left and right. The only way to ensure parallel verticals, or horizontals is to make the film plane parallel with the image plane. If you tilt the camera up to shoot a building, for example, and you want the vertical lines of the building to be rendered as vertical in your image, then those lines will not be vertical because the building and the film are not in the same plane.
See the section "SHIFT MOVEMENTS FOR PERSPECTIVE CONTROL" here for an explanation with visual examples.

But does a PC lens operate in some other manner that I'm not aware of? I always thought that the terms "perspective control" and "shift" mean the same thing for 35mm architectural lenses. What leads you to state that,
