Hyprland is decent, it’s one of the better Wayland window managers, that being said it’s still in beta and not complete. Also be aware, it’s a window manager, not a desktop environment. It won’t do much besides well managing windows, taskbar, start menu, notification demon,… have to all be installed and setup by you and the config is done in text files, not some gui.
Also the community is rather toxic, I’ve made similar experiences to this in the past when trying it out.
I’ve used KDE on my convertible during uni and it worked pretty good. I mean for a GUI oriented setup your options are pretty much KDE, gnome, cinnamon, xfce (don’t know how good that is with touch though) or cosmic (is that out yet? Idk tbh).
Afaik gnome and kde both have good touchscreen support, maybe you’ll need to do some slight modifications, so I’d say just try them out and see what you like.
