Let's talk about fonts.
The first important property of a font is that it MUST be readable. Not like regular text in a book or an email, but readable on a graphic, at thumbnail size, on a small-screen device. Readability requires
–limiting the number of words - I play with phrasing to minimize word count - meme text is like a headline on an article
–placing the text on a clean part of the graphic, or modifying the background until the graphic doesn't compete with the text
–size. I play around with text scale on almost every meme, not only to fit the text over an unbusy part of the graphic, but to make it as large as possible given the style of the meme. I'm ALWAYS thinking readability.
It has been said that mixed-case text is more readable than all caps. This is debatable. I think it depends on the font. 90% of the time my text is mixed-case.
A second property of fonts is what I call flavor. Each font conveys a certain psychological impression, does it not? Visit a site like https://www.dafont.com/ or https://typezebra.com/
Examine hundreds of fonts and you will certainly notice differences.
A font can be dignified, solemn, careless, silly, bookish, it can connote an historical era, it can be ponderous, scant, futuristic, personal, etc. etc.
Does the memer pick a font to match what the meme is trying to express? Or do they always select Impact Condensed all caps to get that "internet meme" look?
Anon asked for some sans-serif fonts.
I troll the free font download sites regularly. On Saturdays. Sometimes I just get tired of the same old fonts and pick new ones. I rotate my fonts. Rarely do I use a system font.
I prefer Open Type fonts if I can get them. True Type fonts are OK too. OTF permits font designers to use ligatures, which allows one to create a different custom look.

Again, if the meme isn't readable (or at least a "grabber" phrase readable) on a small screen device, you failed. They won't click it, and the opportunity is lost. (Of course, some wonderful memes have no text at all; what I'm saying applies if text is present.)
