It's not a massive ask to install MongoDB. Unifi stuff is quite cheap for what you get for a simple reason: Each one does not need to run a webserver and all that stuff. This means that the pretty stuff has to run elsewhere. For a single site you can use a phone app and for multi site setups and MSPs you have the controllers. The controller can be run on a Windows PC with a next next install or a Linux box with pretty minimal setup requirements. It sounds like you might want to go the app route otherwise if you are an IT company (I own a 20 person one - so also small) then find the one screen doc with around 10 copy and paste instructions once you have say a small Debian or Ubuntu minimal installed. You could also run up a Win10 VM and install the Windows distro quite easily.
