In this answer it is said that Boeing (contrary to Airbus) gives final authority to pilots, but the example is about a 747-100(SP). This answer states, that modern Boeings have have a lot of fly-by-wire systems too. After reading over 10 (I think) Aviation.SE questions about the B737Max and MCAS it got me wondering.
How much authority does the pilot have or can the pilot get in modern Boeing planes? (as in how much does fly-by-wire/other electronics involved ignore/adjust/overrule pilot input (or independent commands) in each mode or law.)
Is there a difference between models? (for example 747-8i vs 787)
And how do the laws switch on their on vs pilot forced?
I am not interested what you think is better or are used to, or design philosophy, or stick vs control column.
I appreciate data about 737NG too but consider it an "old" model. I am interested in 777X too but unsure how much definitive data there is.
Correct me if I got my facts wrong and please be gentle, I am a noob.
