Unfortunately in my case, I really need wifi and would much prefer using some sort of internal wifi rather than a wifi adapter.

Well, I think this may be not a bad idea at all. However, what would really stop me from using your search engine is if my search queries (or anything else I send) were somehow tied to me and/or sold to someone. Please don’t be like Google, Microsoft, or OpenAI.

Is it ok if I skip some challenges or do them later? University final exams are comming up soon for me.

I would like to see:

1. Corporations treating their customers like people, not just bags of money.
2. Corporations and employers to stop spying on people. Like, it makes me feel so unsafe and that I can’t really trust them.
3. People becoming more tech literate.
4. Open source software, such as Linux being used by more people, especially those who are not so tech literate.

Ok, then C++.

For me it would be C/C++.

Well, that's how most troubleshooting happens on Windows/macOS as they are just big black boxes with poor documentation. On Linux, most issues can be fixed by the user themselves.
