The 245/40s will be perfect IMO
As for shocks and springs; you need to decide if you want firmer than OEM; as compliant as OEM (as close as you can get) or coilover levels etc...
I test drove an F30 330D with the Bilstein B12 kit (B8s with Eibach pro kit springs); for me is was far too firm for our local roads (superb on the tight/twisty country roads) but normal roads at normal speeds; just too bouncy
i also test drove an F31 340i on Bilstein B16s and again; just too firm (but bloody amazing on fast roads)!
I'm personally not a fan of Koni; had plenty of build quality issues with them in the past (but that's going back to late 2000s); I've had Bilstein shocks plenty of times with zero issues and now my F31s on the B4S shocks with the Eibach pro kit springs; it's absolutely spot on..
It took the pot hole ridden, super-rough roads in the Scottish Highlands with ease and the handling is much better too; however my suspension overhaul was full (ie every arm and more)!
Cost me a fair whack; but I wanted to future proof the car until at least mid 2025 as I've promised to keep it until we've paid our mortgage off
