I have a systemd service with this declaration:
RuntimeDirectory=plex RuntimeDirectoryMode=750 which creates the in memory directory /run/plex.
How would I list the capabilities of this mount point as I would do with mount -l?

The RuntimeDirectory= directive does not create a new mount, it only creates a new directory under the existing /run. So, in a way, you're just reusing space from the existing /run.
In other words, look for /run in mount -l output to see the options of the mountpoint where /run/plex lives.
You can also use the findmnt(8) command and pass it the full path with -T to show where the mount point is and its options. For example:
$ findmnt -T /run/plex TARGET SOURCE FSTYPE OPTIONS /run tmpfs tmpfs rw,nosuid,nodev,seclabel,mode=755 If you want to know how much space has been allocated for the in-memory tmpfs, you can use the df(1) command:
$ df -h /run/plex Filesystem Size Used Avail Use% Mounted on tmpfs 3.9G 612K 3.9G 1% /run
