This is opinion based of course
Poison: Coil is a rare boosting move, akin to bulk up but having an accuracy boost to boot. It's a shame that there's few viable physical poison types (idk maybe a physical venusaur or nido). Otherwise toxic spikes is nice. Practically everything gets toxic so it doesn't get the mention, but otherwise its awesome.
Electric: Thunder Wave, which provides reliable paralysis, and is infinitely superior to the only other electric status move, Charge. Charge Beam isn't technically a status move, but its a nice booster
Fire: Will-o-Wisp Fire types don't get a lot of status moves (the other being Sunny Day), and if you really want sun that badly use Ninetales
Ice Haze Despite being more offensively inclined as a typing, Ice types lack a boosting move, but having the ability to wreck opposing boosting sweepers is by no means a shortcoming. Hail is the other decent option, but Abomasnow is best left for that
Fighting Bulk Up A great boosting move for the generally physically inclined fighting types. Quick Guard and Detect also have some use, but mostly in doubles.
Bug Quiver Dance Now this is tough, Heal Order, Defend Order and Tail Glow are all awesome moves, but Quiver Dance is the perfect sweeper boosting move imo
Steel Shift Gear is like a dragon dance but with even more speed, awesome for the slow steel types. Automize may be used if your despise low kick
Rock Rock Polish really helps with speed. Sandstorm is best left to sandstream, but Stealth Rock is also a key entry hazard. Wide Gaurd's nice for doubles
Ground Spikes is a rarer entry hazard that oddly enough no ground type gets. The other two options, mud sport and sand attack, stink
Psychic Lunar Dance There are so many freaking psychic status moves, so why this one? Fully healing a highly damaged core member of your team is no joke thats why. Dual Screens, Calm Mind and Cosmic Power+Stored Power deserve mention
Ghost Destiny Bond This is the ghost status move with the least situational use, allowing one to dispose of a slower opponent thinking the can muscle through you uninjured.
Dark Dark Void is a reliable sleep inducing move. IMO it ties with Nasty Plot
Water None of them Soak and Aqua Ring are rather gimmicky, and rain dance is easily accessible and redundent with Politoed's existence. Try scald or something.
Dragon Dragon Dance It's the only one.
Grass Spore You said it youself. Stun Spore, Leech Seed, Synthesis and Aromatherapy are also nice options
Normal Shell Smash though one must keep in mind encore, baton pass, recover, nature power (which is a status move btw) and a skew of others
Flying Roost Reliable recovery ftw, and the other choices are mostly subpar or gimmicky
Hope this helps :)
