Smart daily auto-restart (will restart at a scheduled time each day, but give a 30 minute warning period, with increasingly strong warnings, but will restart early if the server is empty ... also prevents players from joining the server at the last minute, also will kick the players a second before shutdown to be safe): https://one.denizenscript.com/haste/80291
Auto-saver (every server should have some auto-saving happening... it's not strictly necessary, but it helps reduce the impact of crashes - this sample script saves Citizens saves and some Denizen data every 30 minutes... you'll want to toss in any other auto saves you need, possibly some
- wait 1slines or similar between them as well): https://one.denizenscript.com/haste/80168
No quick-join (will force players to wait 10 seconds after initial server start before they're able to join, with a pleasant "server is still loading" message - handy to allow things like discord to load) https://paste.denizenscript.com/View/80568
