Optimizing my first serious L2 contracts has been a journey: 1) Dev: your intuitions are all wrong now. 2) Testnet: cheap L2 gas, cheap L1 calldata. Many tools overestimate L2 gas and it can outweigh calldata unlike IRL. 3) Mainnet: cheap L2 gas, L1 calldata is 20-100x testnet cost. Calldata costs dominate everything.

Anything that reduces nonzero calldata bytes will have the biggest impact. The techniques in @msolomon.eth's repo here are all good: https://github.com/ScopeLift/l2-optimizoooors Make assumptions that avoid passing args like reading defaults or values from storage, use packed encodings, use custom selectors.
