Replacing exterior light - mounting issue - single box

Looking to replace an exterior light fixture. See image. Not sure how to proceed due to odd single-pole box.

Do I need an adapter? Mounting plate?

Working with exterior aluminum siding. Previous light used black metal mounting plate with screws into this box...likely 20+ years old.

Thank you for any insights or tips.

That is a cut-in gem box. It's what a switch or receptacle would be in. Good for a light fixture too.
Most replacement wall fixtures will come with a fixture bar that will mount to that box and the light connects to it. Usually it will be the first or second one.

They also make several different mounting blocks that will fit the siding making the light installation neater. You could pull out that box and use something like in the picture below.
