Since you are using a native systemd unit, I hope you have read man
systemd.mount:


Options=
Mount options to use when mounting. This takes a comma-separated
list of options. This setting is optional. Note that the usual
specifier expansion is applied to this setting, literal percent
characters should hence be written as "%%".


I.e. while you can use size=70% in /etc/fstab, you can't use it in a
native .mount unit, but you need to use size=70%% instead.
