We will have to experiment with block times and tendermint consensus related timeout to find a reasonable middle ground.

Update: Increasing the timeouts is no longer relevant but what we instead really we want is: tendermint/tendermint#5911
We should help the tendermint team to get that feature shipped.

The current default timeouts can be found here:
https://github.com/lazyledger/lazyledger-core/blob/b68e2dc394c0fc1840d57b1a763c77c1ef7a13cd/config/config.go#L869-L874

For immediate execution, we might need to increase TimeoutPropose as a proposer would need to execute Tx against the state before proposing. Also, we'd like the block data to propagate through the p2p network (reaching at least some storage nodes (ref: celestiaorg/celestia-specs#3).

Also we likely would need to increase the TimeoutPrevote to allow validators to validate blocks via DA proofs (see #65). (this is no longer planned)

We could start with the current defaults and experiment our way up to defaults where consensus nodes don't end up timing out and starting new rounds without making blocks.
