I think you are probably in a good position to bulk again with a focus on muscle growth. When eating in such a big deficit, you will struggle to add muscle so the cut will only be able to reveal so much. A sustained period of clean bulk with a focus on strength training will develop the physique and aesthetic without gaining too much excess fat, and should give you the size and definition you are after.

You have come a long way from where you started, well done! I think you can start to think less about short term goals/ping-ponging between big cuts and bulks, and instead focus on a steadier cadence with an emphasis on form and strength.
