I would use what Maxim suggest for the displays and would not bother with mods to drive common anodes.
As for the capacitance, well, few centimeters more will not do an harm. Do not worry about that. A 20 meter or more sure is of concern.

My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.
Not as dumb as yesterday, but stupider than tomorrow!

Anyone know about Tayda Electronics? I just found about them now.
They're out of stock on the MAX7219 at $1.99 :O

I signed up for a NOTIFY when that's gonna be in stock.
EDIT: I just noticed they are cleaned out on 7-segment LEDs.
