Honestly, switching search engines is pretty normie friendly. I've got a lot of non-techy friends or family, that use Ecosia or something. They also did it on their own, I didn't even encourage them to do it.
With things like Linux it's a bit harder. But if they don't rely on any specialized software, they are usually fine with me offering to upgrade their Laptops so Linux. I installed Linux Mint on my Mom's Laptop and she can use it as well as Windows. She never complained about it.
