True except typical road double 52 or 53T big chainrings and 42 or 39T small chainrings aren't readily available in 110 mm bcd format and those that are typically don't have the shaped teeth, pins and ramps shifting enhancements.
Toi the OP: would the Force crank really be any lighter than the Apex. Would a change to an 11xXX cassette give you the higher gear you want at less cost?
