Most UEFI devices out there don't have any type of boot menu.

Haven’t seen one PC or Server mainboard without a UEFI boot menu no matter the price range and age. What devices are you referring to?

  I didn't say boot loader, I said boot _menu_. The boot loader may be a mandatory part of UEFI (otherwise the entire thing wouldn't actually work...), but there is absolutely no mandate for having any type of GUI, not even a boot menu. Most devices out there will always boot the first entry (or BootNext) no questions asked. Some devices may allow reordering boot loader entries in their setup program. Almost no devices will actually a) pause booting whenever there are multiple valid entries b) show you a menu where you can choose one of alternatives c) respect your timeout value, choosing the first boot entry if the timeout expires. Incidentally these 3 happen to be the basic properties of what people usually demand from a boot manager.

    And some devices are simply hardcoded to _always_ boot \EFI\BOOT\BOOTX64.EFI, no matter what. EFI implementations are all over the place. It's gotten somewhat better, but it's hard to rely on anything. But we got decorative flames in the firmware setup dialogues now. Flames make computer go fast.

      what kind of exotic devices are you buying to get flames in firmware setuos and not have boot menu? I've only ever got those white in a blue screen firmwares.

        A Lenovo or HPe system won't have that, of course. But I've had plenty of "consumer" boards for my gaming rigs, or handled friends gaming mainboards. It's not all flames of course. But the design of the firmware UI certainly got really flamboyant when UEFI hit the scene while quality of implementation really suffered. It's gotten somewhat better, but now it's getting hard to buy non-enterprise hardware without over 9000 RGB LEDs on there. Sigh. At least the LEDs don't bother my bootloader.

    The whole point is that I don’t want it to pause boot to show me a menu unless the system is broken. Boot should not need to be interactive by default. But every uefi laptop and desktop device I have ever used has a key you can press during boot to bring up a boot menu.

    Both URLs I sourced directly mention a menu. Here's the first: > UEFI allows the consolidation of boot menus from the OS loader and platform firmware into a single platform firmware menu. These platform firmware menus will allow the selection of any UEFI OS loader from any partition on any boot medium that is supported by UEFI boot services. An UEFI OS loader can support multiple options that can appear on the user interface. It is also possible to include legacy boot options, such as booting from the A: or C: drive in the platform firmware boot menus.

That's not my experience. I've only ever seen HP do an actual file browser in UEFI to pick an arbitrary .EFI file, but overall every computer and laptop I've seen has a button you can press to pick from a list of operating systems available to boot.

You might not think of it as a boot menu, but every uefi system I have ever used has a menu you can bring up by holding a key during boot that lets you choose which disk to boot from. In reality this menu has all the entries you set up in efibootmgr. You can also usually see this menu from the save and exit page of the setup/bios page. These entries are about as customizable as grub entries via efibootmgr.
