Maris, interesting observation of yours there. I did indeed select the 250mm lens to isolate the building from it's surrounds, with the knowledge that I would need to be quite a bit further away from the actual building. Inclusion of the fence, for whatever reason seemed important to me.
I hadn't thought of other images, so I did a search, you are correct, there seem to be squillions of images of that particular building. Initially I thought the 90mm would be the go, but walking around I couldn't get the perspective I was looking for. I dismissed the 150mm as it squeezed the surrounds out, but not enough. Rain started coming down rather heavily, so back to the cab in the ute for a wait and re-think of the possibilities. Once outside again, I ascertained I could do worse than use the 250mm objective.
Your description, "the visual unity of the white fence, the bell-tower, and the church itself." sums it up very accurately, better than I am able to do.
I have a pretty battered 4x5" cardboard cutout with which I often walk around a scene, holding it at 90mm, 150mm or 250mm away from one eye. This gives me a reasonable depiction of what I think I'm looking for. Usually I have an idea of what I'm after and pretty much know which lens and film I'm going to use. This time though I just couldn't get there in a hurry.
As an aside, I find the cardboard cutout is not anywhere as useful when thinking about using the 65mm lens. It does give me a guide, but looking at the GG when the 65mm is on, seems to be the best way to know.
Fujinon 250mm f/6.7, I wish. Nope, it is a Fujinon 250mm f/6.3 which I would doubt is no worse or better, than the oftentimes wished for f/6.7 unit. I've been in love with this lens since acquiring it.
I was hoping to be back in that area right now, one year later. Not happening, as we are still in lock down; 22 weeks straight.................
