The difference between the various actions is unclear, unexplained, undocumented, probably inconsistent with core. Affected messages include:

Thanks for the report!
My understanding is that 'suppress' serve the same purpose as wikitext suppression (https://www.mediawiki.org/wiki/Help:RevisionDelete / https://en.wikipedia.org/wiki/Wikipedia:Suppression ).
Essentially, it's an extra-powerful version of deletion granted to the 'oversight' group.
I believe the others are conceptually consistent with core too:
* Hide - Logically (and permission-wise) equivalent to clicking edit on a wikitext talk page, removing a talk page post , then clicking save. In other words, it's no longer readily accessible, but still fully in the history and viewable by non-privileged users.
* Delete - Essentially the same as regular admin deletion of a wikitext page.
