Arch, or any of it's forks, or any minimalist distro should work fine enough (probably not Gentoo unless you wanna spend a month installing all your software.). I run a pretty crappy laptop, on EndeavourOS. It's actually my daily driver, and asside from the long boot times every morning, it runs alright enough.
Oh my fucking god okay.
Here's an analogy. You have a driver that drove nothing but automatic gearboxes, and how he's asking for a beginner car with a manual transmission to get the hang of it.
The reasonable suggestion from someone who drove everything from modern cars to oldtimers would be something used from 5-10 years ago. You don't have to worry about anything really, just get in and drive, learn how to operate the clutch, it's easy, you get the hang of it fast. He drove all sorts of cars and met all sorts of people in the 20 years he's been a gearhead so he understands that he is not everyone, people have different needs, they don't want to deal with issues, and he knows how to make a good recommendation.
The unreasonable suggestion from an oldtimer lunatic would be a rust bucket from the 1960's. Yes, you gotta work on everything yourself and shit keeps breaking because it's a 6 fucking decade old car, but it's ackshually a good thing because there are no computers, it has a mechanical carbeurator and you can take it apart and put it back together with a wrench and a hammer. He drove them for 20 years and only met the same lunatics as him so he believes everyone can do it and it's only reasonable that everyone has the same expectation as him, and that everyone has the resilience to deal with issues like having to dance with the accelerator to not let the engine stall on idle because it's fucked.
You're that lunatic gearhead that's telling a beginner to get a rust bucket. That beginner will get angry when he faces a problem he can't solve because he doesn't have the same knowledge as you do and get mad at all manual gearbox cars altogether.
In other words, plain Debian is also a lightweight distro that would do just as well, Arch is not the only lightweight distro in existence, and having "long boot times every morning" on an Arch install shouldn't be something you get used to, but something you deal with and fix since every other distro,
and Windows, don't tend to have those nowadays, unless you run off of a hard drive.
