On midtower cases I have researched or owned: (edit: I only have looked at quiet cases, ie ones with closed fronts but still decent airflow)
Fractal design R6/R7 has good front clearance for rad, poor top clearance unless you dont mind fans/rad hanging over ram limiting ram choices and being annoying to work on. Front rad only should work well.
Fractal design R5 has clearance for top and front rads, top limited to 30mm rad and push or pull only. Front, like R6/R7 has plenty of room for push/pull with mosts rads and reservoir space without banging into large gpu. But R5 is dated, lacks top filter, and front requires modding to prevent recirculating expelled rad air, but it was fixable unlike R6/R7 lack of top clearance. But if single rad, R6/R7 might be better option.
Phanteks P600 has good top clearance for top rad, but front rad too tight and eliminates room for reservoir with rad with large gpu.
other phanteks have poor airflow, bought evolve, dremeled it to point destroyed it ie like I did with R6, then tossed it.
I used to have a large full tower lian li case, but much happier with smaller midtower cases myself, i typically use 2x240 or now 2x280, more than enough for single titan/2080ti and 8 core intel heater with 700rpm fans, typically 6-8c delta air/water gaming..
