It looks like even though they exist and work, some of the well known communities are missing from the command completion. For example:
trae@cr01a-vyos# set policy community-list BLACKHOLE rule 10 regex
Possible completions:
<aa:nn> Community number in AA:NN format
local-AS Well-known communities value NO_EXPORT_SUBCONFED 0xFFFFFF03
no-advertise Well-known communities value NO_ADVERTISE 0xFFFFFF02
no-export Well-known communities value NO_EXPORT 0xFFFFFF01
internet Well-known communities value 0
additive New value is appended to the existing value
