Outboard of the engines the 410 could carry drop tanks (not so common, mostly long-range escorts up north, escorting Condors and such) or twin WGR21 pods like the 110G has.
Along the belly it could mount 4 external racks for 4x 50kg bombs, left and right of the bomb bay. It could alternatively mount a 2x 20mm gunpod similar to those found on some FW190As, like the 110G gunpod but more curvy.
In the bomb bay it could mount a number of things....
8x 50kg bombs
1x or 2x 250kg
1x or 2x 500kg
1x or 2x 1000kg (special small-casings to fit in internal bay and let the doors close) more commonly just 1
2x20mm internal gunpod
2x30mm Mk103 gunpod
4x20mm internal gunpod
1xBK50 50mm cannon internal gunpod
They could and were used in combination, so you would see the 2x20mm internal gunpod mounted with the 2x20mm gunpod externally, adding 4 extra guns.
There were a number of options for the basic loadout as well.
the A had 2x20mm and 2x 7mm (plus tail guns)
The B had 2x20mm and 2x 13mm (plus tail guns)
Some removed the MGs when mounting big guns packs like the BK5, so there's the option of cannons-only defaults
Some rarer still (but still an option) removed the tail guns themselves along with the rear gunner to save weight -- not common but still an option.
You can see the dizzying possibilities.
[edit: that's all off the top of my head. Forgive any mistakes, it's just a primer of sorts]
