That exists, actually; you're looking for systems like https://libre.computer/products/ that support UEFI by default, so you can just grab a generic OS image and have it work because device enumeration works the same as on PC and not the... "interesting" hard-coded stuff that's weirdly common in ARM. The official marketing is ... I think this is it? The Arm SystemReady program - https://www.arm.com/architecture/system-architectures/system... but I find it easier to just say UEFI.
I'll have to keep an eye on that list, one of these might actually be a solid RPi alternative eventually if they can get good long term OS support this way. All I'm seeing on it right now are somewhat obsolete boards though, 2 or 4 GB of memory at most, LPDDR3 and 4, no wifi chip.
