I'll be writing a guide very shortly on this stuff if no one answers. I have six or seven different models of buck, boost, and buck-boost converters on hand.
The module that you linked to is perfectly fine for your purpose.
An interesting one I have is this one which is buck-boost which can operate in constant voltage or constant current mode. I'll also discuss how much current theses modules can really handle.
This is buck-boost for CC and CV which will easily power up a Vero 18(!) and will operate just fine with 12-24 volts DC input:

With a 12 volt power supply you can also run your fans, Arduino/Rpi stuff, and the like. Some of the modules are half the price as above, a 600 watt module I use for the Vero 29 or any LED up to 80 volts is perhaps $15. I'll show how to set these up.
I'll also shows tips on modding these modules so they can be controlled by an Arduino and tips on rapid prototyping using these modules.
I've been absent lately, not answering PMs (I need a bit of a break), since I'm engrossed in designing open source spectrometery stuff based on the following chips:
