The #Wikidata query to find #ResPublicae accounts for MEPs has been updated on our frontpage:
https://w.wiki/62$8
It now includes languages and political groups so that you can more easily find accounts you want to follow (or mute!).

There still isn't a good way to look for other #EU accounts, because I couldn't find any #opendata dataset listing EU agencies/orgs/initiatives/whatever, let alone their social network handles. Most of the accounts in https://respublicae.eu/explore aren't on #Wikidata yet.
Some might be relatively easy to add, like all the language/country variants of the #EuropeanCommission and #EuropeanParliament accounts. (But these might also be run by distinct entities, like local representation offices.) #EP #EC
