Update the spawn.
I would say we or something the current spawn away somewhere I guess into storage as it contains so much history and then build a new one,
Reason being is its mostly inactive, outdated and just plain uninteresting and ugly. (I mean the resident bit)
Make it easier for new players to get started, e.g. Have a sign at spawn that teleports them to a random place with space to build.
Also make protections easier to get. Currently you have to make pillars, get cords then make a pe (which takes forever) and then set it how you want, maybe make it so a player could make one themselves somehow ( I dunno how, just an idea)
Make it clear when people join the server that we have a plugin that can log what they do, an attempt to reduce the crime by new players as they thik they cannot get caught.
Sort out the economy in a way that pleases the community, not the way the staff tried last time (which eventually turned into a mess when they ignored the community... As predicted)
Go easier on the ban hammer and punishments. Recently a lot of good players have been banned for a perthetic reason. Just remember staff a ban is serious, it's not a toy <object class="emojione" data="

Just afew ideas that popped into my head, don't kill me for having an opinion
