Looking at 
"https://data.geopf.fr/wmts?SERVICE=WMTS&VERSION=1.0.0&REQUEST=GetCapabilities", 
it indeed seems to mostly serve in EPSG:3857

As far as I can see, there are just 2 layers in EPSG:2154 (Lambert 93), 
which is a "proper CRS" for France: HR.ORTHOIMAGERY.ORTHOPHOTOS.L93 and 
CADASTRALPARCELS.PARCELLAIRE_EXPRESS.L93
