There's a huge difference in the political spectrum between France and the United States besides the obvious that France has many more political parties that can classified easily whereas the United States has much fewer parties with individual members within the few parties that would easily fit into some of those Far Left or Far Right categories.
Simply, if something does not exist in the United States...one can identify
a few political members within a party to then say...its "far left" or "far right" party. Just as importantly, those few members that do not agree with the overall agenda of the party
or are publicly outspoken against their political party...
They are removed from key positions within the party.
In France, there actually are "Far Left" and "Far Right" political parties that
walk the talk involving
all the members in the party in which Macron has issues with.
If one want's to refer to Macron as "Left" considering his
prior political socialism views...I'll agree with that but
not "Far Left" with his history of fighting those political parties.
