Like many others it seems, my first experience of "being inside an arcade wave shooter", was Xortex (free in The Lab), & I loved it, so I went looking for other similar games, & found this little gem, which I like even more, very good, highly recommended.

Also similar are space pirate trainer & stardust vr, though this is my first preference as with those 2 you must protect your whole body from enemy fire, rather than just one controller/ship, I find this a bit more fun.
