Sounds like you need to play games like Half-Life Alyx, Pavlov VR, and Into the Radius, which are designed around VR movement and hand manipulation that truly cannot be given justice on a flat display with a controller or a mouse and keyboard setup. A used Index is quite cheap these days, or you could wait for the Frame.
There are even non-meta wild card headsets like Bigscreen beyond, PSVR2 (PC compatible now), and Vive's standalone line.
