About Battery Capacity
I am using 20W adapter for nearly 4 months with my iPhone 11 and my battery capacity drop to 96%. Is this a matter of concern? And should I stick with 20W adapter or should I go for 5W or 12 W?
iPhone 11, iOS 14

Any USB power brick will safely charge your phone provided it is good quality, like the Apple products. The phone will control the charge current, you just need to use a minimum 10Watt but you can use 100Watt Macbook brick if you want.
You should expect about 1% capacity drop per month for a phone where you use most of the battery charge in one day.
They are designed to give a minimum 500 full charge cycles (70 weeks if you use a full charge per day) before dropping to 80% So yours is about average.
