Since the release of the General's Handbook, I've played nothing but Meeting Engagements. I think it's a great format - it's quick, so I can get a game done in a week night with a friend easily. And it still feels very much like Warhammer. But I don't see a lot of discussion here around this format.
For those of you who are unfamiliar Meeting Engagements is a four-turn game mode played with 1000 point armies. These aremies are split into three groups, or contingents - your spearhead, your main body, and your rearguard. These groups come in over three turns - usually in that order, but some scenarios mix it up. Sometimes you start with only your Celestar Ballista in your rear guard out on the field first.
For Stormcast Eternals, some of the more obvious drawbacks of the army are magnified in this game mode. Our model count is really low, and with large bases it's hard to get a good charge in, or compete for objectives. And with only 1000 points, it's hard to cover all the bases.
The rules for reserve units interact in interesting ways with how these contingents are deployed, which is at the start of the battle, and then at the end of movement phases over the subsequent turns. Instead of setting up your rear guard artillery at the end of the movement phase of turn two - you can deep strike them, but then you have to wait until the next turn's movement phase, meaning you miss out on the opportunity to fire with them using the command ability of the Anvils of the Heldenhammer, for instance.
I have a couple of army lists to start you off with.

I like having a leader on a fast mount, like a Gryph-Charger on my spearhead to zoom in and snatch that first round objective.
