There is also Starknet that you could add to your list. SUI and ZK-SYNC seem like the two big ones that may have an airdrop though, it would be good to use those chains for in case.
Sui mainnet will be launch soon and there is no free airdrop for Early supporter or community. Tye only benefit Sui team given to community is allowing discord server member and sui capy winners to join IEO in exchange. All those discord members who joined SUI official discord group before 1 Feb 2023 will be eligible for taking parts in IEO.
Now our focus should be on ZKSYNC and Starknet which can be a biggest Chain in term of transaction and Airdrop. Fee of both chain is very high and you have to pay 20$ above just for official bridge and 2$ above per transaction (Swap, Add liquidity, Mint Nft). i have done all and waiting for mainnet to be launch this year .
