[COD] Which COD game has the BEST and A LONG campaign? first time on cod Question

so now that steam has sales i was looking through the games and i noticed that the cods are preety cheap

i was gonna buy modern warfare 2019 (i mostly want a godo campaign,but the other things are also appreciated) and ppl said it has a great campaign BUT its incredibly short

i want a cod with a good and LONG campaign (like 15+ hours) and also good other gamemodes (like zombies or whatever) but not as important

any thoughts?
