Have not found a solution yet. In fact, if you change the font in Notes on MacOS or iOS devices and later read a page of NOTES on iCloud.com, it resets the font back to Marker Felt for all devices. It is odd that iCloud.com can make a universal change but MacOS and iOS devices can only make font changes that do not reach iCloud.com. Maybe that is a clue for how to find a solution.

At this time the web version of iCloud doesn't let you change the font. It's pretty limited, I know.
You can contact Apple here: http://www.apple.com/feedback/icloud.html and request the feature.

As a work around you can type your data in another application on your computer, select a font, COPY and PASTE your text into the iCloud Notes (from your web browser).
Personally I like the font, "Courier New" becuase it is classic, basic, and very ledgable.
Good luck and i hope they give options to make the Note plain Text, or HTML,
and different font/text styles.
