Yeah - the hw really has to be curated. I havent tried using a machine cobbled together from various parts (custom desktop), but off the shelf quality laptops work fine for me last 2 years or so and have none of the issues you mentioned. Emphasis on quality - not cheapo models. I think if you treat Linux same as OSX and run it on known good hardware supported well by Linux you are fine today IME >HiDPI support is a giant mixed bag I will say that this is still a thing, although with experimental gnome fractional support it works pretty well now. Honestly I have a 2019 macbook pro 15 and have more problems with it than I do with my Thinkpad X1 Carbon 6th gen with Fedora 32.
