All these hacky heuristics like block size are just dancing around the problem, and the natural solution is already present in bitcoin: smaller blocks, (down to the point of individual transactions) each mined. Don't relay things that haven't been mined. As spam or transaction levels go up, mining targets for submission go up too.

You know, you can think of Bitcoin as a system that maintains a ledger
for transferrable hashcash... Which means transaction fees *are* paid in
hashcash.
