A "good quality" 12-point wrench should not be able to damage a bolt head or nut "fitting". Most often, I break the ratchet part long before I damage the "fitting"

This is a set of 8mm to 19mm flex head 6 point ratchet wrenches. That is 12 different sizes.
They also sell individual wrenches.
If you can get a ratcheting wrench on a fitting and it is too tight to easily break it loose, switch to a normal 6 point wrench to break it loose and then switch back to the ratchet. It doesn't hurt to have a set of LONG wrenches to help improve the torque ability of the wrench, but you can also use two combination wrenches together to add length to the first wrench (the one over the fitting). If you don't understand that, I can send a picture of how that works. That way, you can carry a smaller wrench kit with you and still have the extra torque capability to easily break loose a tight fitting.
I also love 1/4" drive socket sets since once the fitting is broken loose, they are less cumbersome than 3/8" kits. Granted, they won't work on 1 inch bolts, but up to 9/16" (14mm) they fit better in tight areas and don't tire your arms over time.
12-point wrenches are more common because they are easier to get settled on the bolt/nut as there are 12 positions available instead of 6 and thus require less rotating room to get it into position.
If you understand that the 12-point wrenches are almost always better, then there are a lot of "cheap sets" available either individually, in small sets or large sets in the US for reasonable prices. Like these:
