You may transfer at AMS only when you are en-route to other non-Schengen states, i.e. US-AMS-UK, as in these cases you do not need to enter Schengen.

You cannot "transfer" at AMS if that "transfer" involves entering the Schengen zone - and taking a flight to France or any other Schengen state involves entering the Schengen zone.

France only allowed non-essential entry to EU nationals (excluding Spain and the UK, which though no longer an EU member state is still in the Brexit transition period) earlier this week; it will take a little while more before 3rd country nationals will be allowed non-essential entry to France. It could take some considerable time yet before the US and EU relax their bans on each other's citizens, so keep that in mind.
