I don’t see how you can do this, because you turn punishment into privilege. If the way to firefighter pay is through a jail cell you create all kind of problems around perverse incentives.
I think the first step is people educating themselves even marginally on the topic of discussion before proposing policy changes.
But it's not just hurting the firefighter market, lots of people just have issues with using prisoners as slaves.
If part of their job description was the equivalent of clearing brush/cutting fire lines in emergencies, I might consider it.

Do you have another source of willing, not-risk-averse, physically fit and competent people that are not doing anything else, know each other already, can be there ready to work together at a moment’s notice, and won’t bail partway through to go fill an instacart order?
Yes -- but -- by undercutting the wages you would have to pay people outside, it lowers the pay of the non-prison laborers. This hurts that community.
You can achieve the same result by paying them prevailing wage. This has the extra benefit of giving them some saved up money to start a new life when they get out, helping them avoid falling back into a life of crime to make ends meet.
