Not saying you have to or anything, and I can understand and respect using something like MX Linux to save time on the customization. Just know that because it's based on Debian, any core OS updates will be delayed while the MX team rebases them into their fork.
Honest question, but why not just install Debian with the Xfce DE? Why rely on a fork for updates?
From what I can tell both by testing MX Linux and by reading about it, it's nothing more than Debian with a few pre-installed packages and some customization. All of which could be done on Debian directly without much trouble.
That's for everything listed above. This is measured straight from my UPS which everything is connected to.
