I don't know much about what I'm doing, and I need help. I'm trying to cut a hole in my wall for a 1 gang low voltage bracket. Do you know what type of wall this is? It's very hard to cut into with a drywall saw. Do you perhaps know how I can cut into this easier?
I think you've answered your own question.
The first type of mount is for screwing into a stud, the second is for drywall/plasterboard.
You can still use the first type though.
Cut the hole for the switch in the drywall and then cut a length of batten just longer that the hole. Then fix this to one side of the hole inside the cavity. This is the tricky bit as you might end up having to screw into the batten through the drywall, which is going to leave you with a couple of screw heads to cover. If you can use an adhesive that should work as the bracket and light switch aren't very heavy.
Once the batten is firmly secured, fix the batten as illustrated on the web page.
However, I would first see if you can arrange an exchange.
It looks like a "Triple Grip" brand anchor. I have similar anchors. The box says 77 pounds in 5/8 inch drywall. No specification for 1/2 inch.

That's a normal wall, sheetrock over plaster. That's how you save money when you want to renovate your home with plaster walls in bad shape, you just screw gyp board on top instead of paying for demo/dumping then gyp.
run your finger around the back side of the plaster inside the wall, you should feel some lath or if the lath is nocked away, you should feel flat/bulge/flat/etc.
Also, that's not insulation. Insulation is like cutting through butter. That's plaster. Delicious dusty plaster.
It's fine to cut into with a drywall saw, and it's normal that it will destroy your drywall saw. Most people just use whatever they have on hand, and you just have to decide which tool you want to destroy.... you can get purpose made masonry blades for your tool of choice, but then you have the tool of choice cost on top of the blade, and a drywall saw is so cheap to begin with. Cost of "replacing" drywall saw you already have if you're really sad it's not sharp as new versus: Cost of reciprocating saw and masonry blade; or, Cost of masonry reciprocating saw blade and replaceable blade handle that accepts that type of blade; or, Cost of oscillating multi tool and masonry blade.
