No. I think you are correct and mostly even wifi hardware works fine, at least compared to *BSDs. I use Linux across a wide-range of machines, both desktops and laptops, with mostly very recent components. The only other unsupported hardware I have personally come across is some gaming hardware (e.g. Thrustmaster racing wheels) and an add-on sound card (Soundblaster AE9). And of course, some things like DLSS3 with Nvidia do not work.
