Some recommendations I would suggest are: -Linux-specific laptops (HP Dev One, System76, etc.) as they are built specifically with running Linux in mind. -Framework Laptops, as Framework has worked hard to make sure Linux works well with their devices. -ThinkPads, as their hardware usually tends to work really well with Linux.
I personally use the Framework Laptop 13 running Debian, and I love it!
This might be cheating a bit since I am a computer science student, but we have Linux servers we can access for classes, and our university library has a maker space that has some computers running Ubuntu in it.
For a while in middle school I would spin up Ubuntu or something similar in a VM just to look at it, but never really used it. The first time I really used Linux was Raspbian on my Raspberry Pi 2 that I got in 8th grade. As I went on tinkering with Linux, I eventually replaced Windows with Ubuntu on my HP Stream since it ran better, and by my Junior year of high school I was daily driving it. Now I’m using Parrot OS Home on my laptop and GhostBSD (I know its not Linux, but Linux led to me trying it) on my desktop
