You cannot. You have to order your service explicitly "Before=" all services you you wanted to be run before. THis then implies an ordering at shutdown too, as the shutdown order is always the reverse of the start-up order in systemd. THere's no concept of running things "first" or "last" during boot-up or shutdown, and there's no concept of freezing execution of other units if yours is running, as that would be pretty weirdly defined in a mostly parallel scheme like systemd where connecting to another service or invoking another method on another service might result in automatic activation. Hence: figure out exactly what you want to be ordered after at boot and place that in the After= line in the unit file. THen figure out what you want to be ordered before, and add Before= lines for that. THen, look at your shutdown, and order yourserlves After= everything that you want to be stopped before, due to the reverse-order-at-shutdown rule...
