I travel a lot and have definitely tested a few cases. If it's going into the hold, hard shell from a reputable brand. I put a security strap around it as well to distinguish it. I rarely use black for the aforementioned reasons. Soft cases are too easily damaged and can get soaked through in a heart beat. Don't get the absolute biggest as it's easy to exceed the permitted weight.
For peace of mind, I throw an AirTag in it so I know where it is.
Since Covid, I have not checked a bag in so have now reverted to a cabin size spinner.
