As the chain state goes larger and larger, it gets hard to export/fetch the chain state.
Are there any other tools aside from fork-off-substrate and try-runtime for performing a runtime migration?

fork-off-substrate does not work for large chain state indeed.
The try-runtime CLI got moved into its own repo try-runtime-cli with documentation linked here.
We use this regularly in CI and it works well for Polkadot and Kusama. For very large states >10GB it will need some adaptions, so it depends on how large your state currently is.
