My first gravel bike came with 42t crank and 11-42 cassette. It's perfect for everyday use. You spin out at like 45km/h (or even higher if you can do high cadence) while the 1-1 gear allows you to climb pretty steep hills. Sure, it's not enough for a road race and I prefer 2x drivetrain these days as I do a lot of distance on pavement but I still think 1x is just a better option for most recreational cyclists.
