How to increase iCloud Storage further than 2TB

Subscribed to Apple Family bundle (the higher $19.99 is not available in my country) which only includes 200GB iCloud. But since I still have the 2TB iCloud, it now appears I have 2.2TB on my iCloud storage.

I am way past the AppleTV+ but enjoyed my first year free. Especially with Ted Lasso returning and my SO is enjoys the new series, Physical. Since I also use enjoy Apple Arcade, it is cheaper to just get the bundle but still keep the 2TB plan. I’m not sure if Apple will reimburse me for the remaining weeks that I paid for Apple Music and Arcade. I hope they do since I only paid for those in the last two weeks.
