If we plan to code new landing page templates with a variety of predetermined font styles in the CSS, is there any possible way to make those formats available (similarly to H1,H2,H3 already included) in the WYSIWYG editor? Or do we just have to provide everyone some instructions on editing the HTML within the rich text editor?
I believe if you define the H1, H2 H3 (etc) styles in the CSS of your template, the styling will be called once you publish the landing page. It may not always display the correct styling in the editor panel, but should come through on the live page. This is assuming you are using web-safe fonts, of course; I wouldn't expect custom font types to work well anywhere.
