I've been struggling with some servers that have what appear to be less than optimal UEFI implementations for booting operating systems other than Windows Server. It struggles when booting Linux distributions such as Unraid and TrueNAS SCALE, etc.
I'm familiar with options such as OpenCore, GRUB, Limine, and rEFInd, and a few others that seem to specialize for embedded applications, but I've not found a silver bullet yet that has solid OS/kernel autodetection and just seems to work everywhere. I have in mind that it would be nice to keep a number of identical USB2 flash drives that seem to reliably boot to a good UEFI implementation that can autodetect and facilitate selection of any OS (and remember a selection once selected similar to OpenCore's
Are there any other options that might be particularly noteworthy and accomplish my desired goal?
