Short answer
One more year changes several lines at once.
A final work year can add savings, delay withdrawals, shorten the health-coverage bridge, and change the Social Security claiming window. It can also add one more year of taxes and work income.

What you actually came to find out
Plain answers first. Sources stay below for checking details.
What gets better?
More saving time, fewer withdrawal years, and possibly a shorter Medicare or Social Security bridge.
What can get harder?
Another year of work may delay the life they are trying to start.
What changes the math?
Income, savings rate, health coverage, Social Security timing, taxes, and spending.
What is the clean test?
Compare the plan retiring now with the plan retiring one year later.
Savings
One more year
A later retirement can add contributions and delay withdrawals.
Source trail: IRS: Retirement Topics: Contributions, Morningstar
Social Security
Timing
SSA estimates depend on earnings history and claiming age.
Health coverage
Bridge
HealthCare.gov and Medicare.gov explain coverage before Medicare and sign-up timing.
Source trail: HealthCare.gov, Medicare.gov
Taxes
Income year
IRS annual tax and distribution rules shape the work-year and retirement-year tax result.
Source trail: IRS: Tax Inflation Adjustments, IRS: Publication 590-B: Distributions from Individual Retirement Arrangements
The useful comparison is not work versus retire in the abstract. It is this year of income against the bridge years, plan odds, and life you want.
Neutral landscape
The shape of the question
The Social Security source matters because one more work year can affect earnings history and claiming age.
The health source matters because a later retirement can shorten the coverage bridge before Medicare.
Source trail: HealthCare.gov, Medicare.gov
The account source matters because one more year can add retirement contributions and delay distributions.
Source trail: IRS: Retirement Topics: Contributions, IRS: Publication 590-B: Distributions from Individual Retirement Arrangements
The withdrawal source matters because the plan road changes when withdrawals start one year later.
