Priority?

Out of all the fluids in the car, what should be replaced first to last? Sorry, genuinely asking because i have fuck all knowledge about the cars and the mechanic says almost all the fluids have expired. When i saw the colors some were greenish, some were red and so on. So, asking you guys to have a better understanding about the matter. Also, not trying to get ripped off lol.
Thanks a lot.

oil. the rest is basically snake oil

Just a note on the coolant -- A family member was proud of always checking the freeze-point of the antifreeze in his 1960s tractor, and the fact that he was able to keep the same antifreeze in the tractor for twenty years. He should have also been checking the PH (acidity) of that coolant.
Coolant can go a few years beyond the recommended change interval, but if left too long like his was, it will turn acidic and chew its way through the radiator. The radiator on that tractor has suddenly developed pinhole leaks in multiple places, and it's going to cost him $600 to replace it.

Oil, Coolant, Transmission Fluid, Brake Fluid, Steering Fluid.

Says in the manual. If it's newer than 2015 it's good to halve the intervals and do "maintenance free" transmissions every now and then too.
Generally though, engine oil is the most important by far. In my opinion transmission oil and then axle oil is next. After that, power steering fluid. Coolant and brake fluid is last on the list, just make sure there's enough.

Oil first, the rest can really wait unless you’re experiencing issues. Maybe brake fluid? But even that isn’t an emergency unless you’re experiencing braking issues realistically.

Most cars have never got the brake fluid replaced. It's really only a problem if you're braking extremely much to the point that it starts boiling.

Engine oil, brake fluid, coolant, transmission fluid, power steering fluid, differential fluid... in that order, IMHO

Somewhat depends on the car. Oil is the one constant, always prioritize oil changes. Some transmissions are really picky and have short intervals, some don't. So that's next, IF it matters to your car. Then brake fluid and coolant, then power steering, then differential fluid if you have a dedicated differential or transfer case.

Depends on the car, engine oil is always first, and if it has hydraulic power steering that one is last. But fluids differ quite a bit between cars.
