Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

When you say range, I gather you mean in-out travel. FDs don't vary all that much in trael range, though some are more generous than others.

Usually FD range problems aren't the FD, but the position of the crankset too far from the frame's centerline. Standard chainlines (measured from the center of frame to center between the inner and outer rings) are someplace between 45 and 50mm. FDs are designed around those standards, so if the chainset is too far beyond 50mm they won't reach.

Take a look at the chainring/chainstay clearance and if you have 5mm or so to spare, talk to the dealer about moving the crank in. The method for doing this varies according to the crankset and bottom bracket.

BTW- if you only need a hair (1mm+) you can sometimes get it easily with a file. Find the exact place blocking more outward motion and see if there's material that can be removed. (this varies by FD, so it's up to you to check).
