Tire sizes for light duty touring

I am setting up a 96 Bianchi San Remo for light touring and I am not sure what tire size to go with. I think the bike will handle a 700x35 but I know I do not want to go that large. I am thinking about a 28, 30 or 32 and am leaning toward a 30. I intend to target paved roads and do not intentionally plan to use gravel or dirt roads although I realize there might be times I could be faced with unpaved conditions.

Would like some opinions on the good, bad and ugly of the tire size range I am looking at.

If you will be on paved roads almost all of the time and on gravel roads only occasionally, 28s or 30s should be fine.

Bear in mind that not all tires of the same size are actually the same size. When I replaced a worn-out 28 mm tire last year, the replacement 28 made by a different company did not fit in the frame! I has to use a 25 mm tire (which is several millimetres wider than a 25 mm tire on my other touring bike.)

28s are fine, very cush even for dirt roads and gravel. 32s are even more cush. 28's are NOT suitable for softball sized riffraff, but you'll likely be fine whatever you choose.

28 is the usual size for hostel style touring on mixed roads and works well enough on hardpack trails. 25mm would be OK for good quality roads. As observed already, 28mm designation seems particularly variable ranging from actual 25 to 32mm.
