Other limitations are that modern Adobe products will no longer install on Windows 10 LTSC as it is based on a too old version (but there are workarounds).

WMR situation isn't great but there are ways out. If you have a NVIDIA GPU then you can use Oasis on Windows 10 LTSC (AMD GPUs require Windows 11 24H2 for Oasis). Also on Linux, support for WMR devices has improved markedly via Envision / Monado, but some tinkering is required and it is still behind Windows.
