   Thanks for the review. I've pushed dc1559ce8 for the comments above. The PR 
description has the updated benchmark table and test list.
   
   On comparisons, you're right. `SELECT id, n < CAST(txt AS INT) FROM cmp` 
fails in Comet under ANSI where `n` is NULL and `txt` is malformed, while Spark 
returns NULL. `WHERE n = CAST(txt AS INT)` happened not to fail, since the 
inferred `isnotnull(n)` and the lazy `AND` skip the row first. I'd keep it out 
of this PR since it is already large, and opened 
https://github.com/apache/datafusion-comet/issues/7468 for it.
