This is just a warning, and does not affect anything. Naturally it
should be fixed though. Potential fix posted in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1105029
A more complete backport of MDEV-19210 commits would be required to have a serviceable Galera with systemd.

> The second was from the error log which stated that the service was unable to read /etc/mysql/rest/keyfile.passwd, which turned out to be a permissions error on /etc/mysql/rest which was 600 and not 700 (I checked the other servers and theirs were also 600 so I guess it's the fix for MDEV-36229 which caused that)
yes, directories should have execute permissions.
