@eniko so, disclaimer, I don't know if this is useful advice to your situation, but I found these to be handy on a project I worked on a while back:https://lxjk.github.io/2018/03/25/Improve-Tile-based-Light-Culling-with-Spherical-sliced-Cone.htmlhttps://wickedengine.net/2018/01/optimizing-tile-based-light-culling/iirc we used a modified version of the spherical-sliced cone test combined with the tile depth bitmask strat for dealing with depth discontinuity. this was for culling reflection probes though, not objects.
