Well the question "how often the host OS (Linux) accesses the microSD card" cannot be answered by anyone. I am no Linux expert. And of course this depends mainly on the type of containerized application that is in use.
My personal opinion is that if this is just an idle running Linux OS with no container the only reason to write to the SD card is the system log file written on any special event from time to time.
If you have a container running then Docker starts to write own log files to the SD card additionally. Especially if a container application usually outputs console information you see normally on your screen when running the container manually then this will be written to the log file instead of the screen. So in any case you have to take care of the application that is running additionally on netPI.
The worst case scenario of course is if your application is a database application. In this case any write to the database will lead to a write of the SD card.
