> the screen resolution is much better (I need lots of pixels for the larger fonts I increasingly need)

Xorg supports some scaling methods that macOS doesn't, which meansv you can scale fonts arbitrarily without a HiDPI screen. As someone with severe (but so far mostly correctable) vision problems (high myopia, mild astigmatism, small cataracts, some photophobia, moderate colorblindness) who has used recent MBPs, 1080p is still fine for me on Linux laptops. I don't find that vthe fancy Mac screens really add much in terms of readability, as nice as they are.
