I’ll supplement your observation about modern task force size with a comment about “steaming” as an anachronistic way to describe Naval propulsion in the 21st century.
Not really, if you consider that nuclear powered craft use steam-driven turbines. Nuclear power is just modern steam engines.
Nuclear wessels, carriers and subs, still run on steam. So I guess a portion of the ships and boats are steaming their way still.
CVNs and SSNs us nuclear power to create steam, which provides propulsion. Steaming is appropriate in their case.
