I have also jumped into a vanguard-style 1K list (full-well knowing the massive power imbalance vs a significant portion of armies out there).
My primary goal is just painting up a small force of models which I find are among the best looking in the range (palladors, Aquilor, hunters), and to use them in friendly games with people who won’t net-list me with the latest shenanigans. I am not even considering the one good unit in the vanguard chamber for now (longstrikes)
Going on to strategy, I have tried to read up on every Vanguard thread/reddit/blog post possible... needless to say there’s not much since most are focussed on tournament lists and (non-Longstrike) Vanguard is definitely NOT synonymous with tournament lists. So my advice is arm-chair Generalship.
That said, at 1K you will not be able to do all the things you want. Your list has decent shooting power, primarily to take out support HQs or weaken the tougher, elite units.
I agree with the above post by NauticalSoup - keep your Aquilor, longstrikes and birds on the ground, as well as your Palladors since they can ride the winds. Your biggest issue will be getting double turned, with 6 drops you are probably getting to pick deployment order less than half the time, so smart opponents will give you T1, protect their assets from your shooting as best as possible, and then hope for a double turn to run at you and tear you to shreds.
How you play the list depends a lot on your opponent and the battleplan, but generally my understanding with vanguard is you do not engage, but rather keep your distance, and bait your opponents into making poor game choices.
At 1K, most strong lists have one big scary unit/Death Star, sometimes two. Additionally they have support characters to buff them up. I saw a dual Keeper of Secrets list that would absolutely rip your list apart, but that’s the risk you take with Vanguard... to be honest it would do a number on most SCE thoigh
Other examples are FEC or Death, who can bring a nigh unkillable HQ beatstick, as well as big horde of something.
I feel these are all very difficult scenarios for your list (worse for mine).
Vs a more fairly-matched opponent, you would use your Shooting to chip away at the HQs or elite units while grabbing objectives, and causing target priority issues. Try and pick your engagements wisely, none of your units are significant damage dealers.
I have rambled on much to long already, but the last point I have is try and find some “high-level” general AoS tactics. A lot of it involves positioning, movement and things that almost players never consider. There was a great article I read some time back but can’t for the life of me find it again, and it was really eye-opening. If I find it I will post on here.
In summary, good hunting and good luck!
