This is a great list. A couple to add:

Necromunda is an FPS which plays like Titanfall 2 in 40k, so excellent moment to moment gameplay, some really cool levels and set pieces highly recommended.

The proper old school Fire Warrior which is an FPS I played probably 15 years ago no idea if it holds up today.

If you have VR Battle Sister was pretty fun nothing special but holding and using a bolt gun up close was awesome.
