There is a very convenient node Filter by Actor Tag | Unreal Engine Documentation (or similarly, Filter by Tag | Unreal Engine Documentation), but I just couldn’t find it in blueprint editor when right-clicking my mouse. Did I miss something or is this doc page outdated?
The nodes you posted are for different tasks/blueprint types. I think you have to use something like HasTag or HasMatchingTag. Maybe FilterArray. Did you look at the documentation Gameplay Tags | Unreal Engine Documentation
