From cruise altitude (for e.g. FL370) to the glide-slope interception point (for e.g. 2000 feet), preferably in feet per minute (for e.g. -2000fpm)~

Yeah, about that. 2-3000fpm. At that the slippery sucker is sliding down hill at Vne, unless you start using the brakes.
500fpm is usually minimum and 1500 is more like minimum expected.
Sometimes ATC calls for a descent from economical cruise altitude a long way before the economical descent point, if that happens the crew is going to want to minimize rate of descent (500fpm) until the ATC calls them on it. Stooging along at FL240 while still 200 miles out wastes a lot of time and fuel.
ATCs expect all heavies to be able to descend at very similar rates.

At idle power in order to save fuel a typical descent will be in the 3000-3500 fpm range on most airliners. This is done to save fuel by keeping engine power applied at higher altitudes (where the engine is more efficient) and then descending at the lowest possible power setting and using minimal power until the approach segment.

yes! around 2000fpm-2500fpm.! and decents..... if higher than 2500 fpm, the plane will be in great speed!

500ft a minute
