I can tell you that from CDG, KL is very often way cheaper than AF. Same for LH, they are more expensive ex-Germany than from neighboring countries.
Normally I fly from OTP, so I have in theory the flexibility of choosing many airlines and the competition is on many routes quite strong (including from LCCs). But I also checked randomly a few destinations with layover in AMS, including from Germany where you would assume they would price more aggressively to counter LH, but it was similarly expensive without exception. No “Business Standard” or cheaper fare in any combination, including direct options ex-AMS and with layovers from various European airports. 🤷♂️🤷♂️
