Choosing what concentration of a chemical to buy should be determined by the technical need, not by how sloppy you can be with it. You shouldn't be sloppy with any chemical. If your application needs 1 M, buy 1 M. If it only needs 0.1 M, buy 0.1 M. You can also buy a more concentrated solution and dilute it depending on your skill with dilutions, the amount you need, and your budget. You haven't told us what you're trying to do with sodium hydroxide, so this is why you're not getting recommendations. Nobody here is going to tell you it's fine to be careless with the more concentrated solution.
If you are going to be handling more concentrated caustic solutions, buy a good pair of thick rubber gloves. Don't use surgical gloves or nitrile gloves. And wear safety goggles, and have white vinegar or something on hand for neutralization. These are all available cheap at any hardware store.
