Com-tiles[1] also looks pretty good, a bit more optimized than pmtiles.

The whole cloud optimized vector tile/data space is next after COGs (cloud optimized geotiffs). Point-clouds are also getting the index-range-request treatment as COPC[2].

The COMTiles design has a very neat idea for batching requests directly on the client due to its ordered layout; this should also be possible in PMTiles spec v3 which introduces an optional Hilbert ordering on disk, as well as index compression and optimizations for run-length-encoding of repetitive tiles. I'm hoping to have this ready and implemented in clients by the FOSS4G conference (late August)
