1 - Raspberry Pi selection; I see that both the RPi 4 and 5 are supported in any RAM configuration, please advise which is the most usable based on the below;
1.1 - RAM - What is the minimum amount of RAM for the setup to be fluid?
1.2 - Pi 4 or 5? Assume Pi5 as the clock speed is higher
1.3 - I would be looking to use the MacArthur HAT and Daisy HAT, There only seems to be cases available to purchase for one or the other, not both. And also only seems to be available for the Pi 4? Have zero experience with 3D printing and design, so this would most likely not be a solution for me.

Are you going to use the Pi to run Opencpn or just as a data collector/distributor?
   -As a data point, a Pi4 with 2GB ram is all you need.
   -Pi5 has much better GPU to run Opencpn with mbtiles
   -Ram wise 2 is OK, 4 is good, 8 is probably not needed.

   -Once you add multiple hat, you are on your own for cases. But read this:
