Where do the new units stand in the meta and The List?

All of them Tier 1 except Cecilia

I would definitely put W!Eirika as a tier 1 unit with the abuse she can do with CC + Absorb + Wary Fighter in arena or go Savage Blow + Pain.

And Cecilia Tier 2... Not Tier 1 because she doesnt dispose of Brave weapons At her classe, like jakob's.
But has incredible bulk that can be combined with fodders of wary fighter And good Free skills.

With good investiment , she is great support by CC And smoke skills. Dont need fighter skills unless You change dagger.

Tier 1 is for unparalled Power, but she lacks At using Brave weapon.
She deserve Tier 2 IMO

Just some brief thoughts:
Eirika: will have some effect on the meta, but she scores significantly worse than typical duel skill units because her special is only 200-300SP and she can't use super-rallies and she doesn't have a prf and she doesn't even have 170BST. Also, she's not easy to merge (though also not as hard as a legendary). Probably the main things are that armour teams spamming wards will now have a healer and there's such a thing as a wary fighter healer, which will probably afford her some protection against the null dazzle ability which is coming.

Fae: doesn't really bring anything new. Falchion still rips her to shreds; armoursmasher too, just like M.Grima.

Ephraim: possibly the best slow blue armour in the game? I mean, 32 res with a boon and no merges or buffs; 36 including the weapon; if he goes for fortress res as his seal (and why not unless he wants QR - his atk is already through the roof) we're up to 41. And he can take DC + glimmer + wrath or wary fighter on it. Or bonfire + special spiral, especially if we pulse him with L.Hector. His closest competition is...B.Hector I guess? B.Hector plays for 2HKO on either phase, which means opponents can potentially double through him because he probably doesn't try to stall the opponent's special.

Cecilia: probably affects the meta significantly. Colourless unit with W.Tharja statline; available for free; can debuff the heck out of everyone with smoke dagger or maybe buff up her teammates (who may have upwards of 50HP, potentially even 60 with blessings) using rogue dagger; could alternatively go for something like dusk uchiwa + vantage and completely screw over the horse meta in AR; very tanky herself; access to special fighter or wary fighter making her extra hard to take down or even bold fighter to leverage her solid atk and strong res for a huge glacies. We might start to see raven mages actually go for daggerbreaker.

W!Eirika can't be Tier 1 or 2 when I already killed her in my barracks.
*Thinking emoji*

Eirika is mediocre. Staff users don't want the movement restrictions of armors, and armors don't want the skill restrictions of staff users. She ends up with only half of what makes each of those classes good, and the two halves don't work together.
