I like the distinction of the groups. 

I havent listened to the deep dive on Muun and how exactly it handles everything in the background, but it definetly seems to be in its own category. 'Hybrid" considering it also handles on chain txs

I use Zeus too! It is great as an interface for my routing node, but I consider Zeus, Fullynoded or Spark in another cathegory of wallets, in the node-interface-side.

So I believe there are 3 types of LN native wallets: 
- Custodial: WoS, Bitcoin Beach etc
- Lightning wallet nodes: Breez, Phoenix, Blixt
- Node interfaces: Zeus, Spark 

Muun would be in a non LN native wallet cathegory. LN friendly? Something like that

What is your favorite mobile full lightning node wallet?

if by full lightning node wallets, you mean a wallet that is non-custodial, i recommend Zeus.
iOS and Android apps available.  Android app isnt on playstore need to download the apk from their [GitHub](https://github.com/ZeusLN)

TOR built in,
on chain balance coin control
lots of other expected features of a lightning wallet


edit:
realized after post this is not what you are referring too.
still highly recommend zeus

i use phoenix and muun for any lightning custodial needs.
