I can only fit at Max a 280mm radiator on top for exhaust but I can fit a 360mm one for the front intake so what should I do for best temps?

The 360 up top is probably the way to go. Try to have positive pressure in the case to help with dust though. More air intake than exhaust, that should help with thermals too. Not sure if the bottom of the case has places for fans, but maybe an intake at the bottom to kinda even things out...

Typically, an exhaust would be preferred - that way you're not blowing hot air over your components (after intaking through the RAD).

That being said, there are other factors at play
1. What case, specifically? What does airflow look like at the front? Just because you *can* fit a rad, doesn't guarantee it makes a whole lot of sense.
2. Are you providing airflow elsewhere? Ie if you use a 280mm on top as exhaust, are you using front intake fans too? If not, your other components will see minimal airflow.

If it's either/or, just know it's not a big difference either way. You're talking within margin of error differences, maybe a degree, depending on your components. Exhaust is going to get rid of heat in the case, if you have good airflow, it may get warm/hot to the touch, but that temperature you feel is only a fraction of what your component temps are. If you go intake from the front, you're pulling the coolest air into the radiator, that gives you the bigger delta, but remember that delta is only gonna vary by a few degrees at best. Is this gonna be an AOI?

It is going to be an AIO inside a FRACTAL DESIGN MESHIFY C I will have 3 exhaust fans 2 on top and one on rear with 3 fans on the radiator for intake
also if I I use a 280mm radiator on top for exhaust I will still have 3 120mm fans in the front for intake and 1 120mm fans for another exhaust in the back
