There is basically Windows Home, Pro and Pro for Workstations. There's also Enterprise and Education, but those seems to be the same as Pro for Workstations, just distributed differently.
Windows 11 Pro is about $150 from official channels, or $30 for a key from a reseller, and the key can just upgrade your Windows Home install. It doesn't automatically fix everything, but it gives you the group policy editor which lets you permanently turn lots of things off. It also generally treats you more like a responsible adult, e.g. giving you more control over windows updates.

Because using a pirated key on a Windows I downloaded from Microsoft is a lot less likely to introduce trojans or viruses on my system, compared to downloading a pre-cracked Windows from a a pirate site.
