Hello, Jernej!
It seems to me that if any materials were developed for social media, they would not usually end up on Wikimedia Commons :) Their life span is too short - to attract attention, and (maybe) sometimes they will even be on the border of copyright violation... and even out of scope.
Maybe something like this fact sheet will be useful? https://commons.wikimedia.org/wiki/File:Wiki_Loves_Monuments_Fact_Sheet.pdf
(You can also post parts of it, like separate facts, like: - this is the largest photo contest in the world (and a picture of Guinness World Records seal https://www.guinnessworldrecords.com/world-records/largest-photography-compe... ) - more than 40 countries are taking part in it (and a map https://commons.wikimedia.org/wiki/File:Participating_Countries_WLM_2019.svg) and this is the first time Slovenia joined - Slovenia has xxx monuments, and only xx are illustrated (or some other locally relevant statistics) etc, to motivate people and make them aware)
This video is not country specific, so it can be shared. But you might want to translate the subtitles: https://www.youtube.com/watch?v=SnzQf9VbH9g On Commons: https://commons.wikimedia.org/wiki/File:Wikilovesmonuments.org.webm
Our team has been posting pictures from the previous years as a countdown for the start of the contest, but they are not really reusable, I am afraid: https://commons.wikimedia.org/wiki/File:WLM_in_Ukraine_starts_in_2_days.jpg Especially as you are doing your first contest...
Overall, this category was supposed to be useful for situations like that, but I doubt it is populated enough and regularly: https://commons.wikimedia.org/wiki/Category:Documentation_for_Wiki_Loves_Mon...

Dear all,
we're organizing WLM in Slovenia for the first time, and I was wondering... does anyone have any promo imagery for publishing on social media that I could adapt to our language? Browsing Commons yielded nothing.
Thanks,
