Easy fix to what you need.

Enjoy
Not sure if you are recommending CustomNameplates instead of ModUI for the nameplates, the reason I love the one from mod UI is because of the style(is not shitty like CustomNameplates) and it also has a casting bar with it. I use ModUI solely because of the nameplates and I can't wait for the update from modernist to just enable that part of the addon since I still get a lot of error that I have no idea how to fix because of addons compatibility
For debuffs I use LunaUnitFrames + TinyTip. I dont want to see all the debuffs in my screen anyways, that would be a shitfest in BGs, Luna shows me the debuff in my target and if I need to check the debuff without targeting someone else I just mouse over the person and TinyTip does the job
