nit: can you specify that the three-part name is necessary for UC tables and two-part for HMS?

default 100 seems high, how about 10 instead?

What happens if a user passes in a table name that already has backticks, like "main.default.people"?

I assume the backticks are literal characters in the name (e.g. an MV whose catalog is named main). To address that correctly I double internal backticks, so such names are reachable.
if the user meant "main.default.people" and pre-quoted, they'll see a not-found error.

Shall we do something like
if len(rows) == 1 {
fmt.Fprintln(out, "1 row")
} else {
fmt.Fprintf(out, "%d rows\n", len(rows))
}

I think you can use cmdio.RenderWithTemplate, generate the template based on the data you receive from SQL query and pass it to RenderWithTemplate
Thus you can reuse existing rendering code and get all of the benefits for free
