I've been cutting on tablesaws for twenty years. I haven't had this
problem before, and I don't think my technique is the problem. I
always push the board against the fence as well as forward, and when
possible, I use a featherboard to keep the board against the fence.
The cuts still wander.

When you tested parallelism between blade and fence, did you rotate and
check parallel for a full 360° turning of the blade? I had a warped blade
once caused by a wood chip that had found its way between the arbour and the
blade when I changed the blade.
