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.

Also the fact that different L2s have different calldata optimization/compression, and also all of this is going to drastically change post-4844. It's weird profiling L2 contract costs with so many temporal caveats "today it'll cost X, in a few months probably Y, in a year probably 1/100 of that"
