To add to this list, I still think that Lenovo makes great and very customizable Thinkpads. As far as I know, the P15 is one of the popular ones. It's a chungus though, so if you need something lighter, the X1 Carbon is a great choice as well as it's very compact and portable.
System76 makes bespoke Linux laptops, they could be an option.
