Great choice, better even than Idris Elba
because Idris wants to be a hard action hero like what he's doing in Hobbs & Shaw, OR alternatively, politically active material.
Bond might be a bit boring for Idris, and too limiting for him (as he is a producer).
Congratulations to the Bond team, I think the franchise may be again reinvigorated by this. THE REASON Bond is still around is because the people running it know WTF they're doing.
