Bear in mind Meowscarada is about as strong as Cinderace on statline (with a slightly-higher and very relevant Speed advantage), so new moves would definitely get it a lot of mileage vs the other Protean Starters.
The thing I actually like about the Paldea starters is that, by design or coincidence, they highlight the three "flavors" of Tera usage when looking at their HA roles. Meowscarada with Protean already does type shuffling and actually isn't (always) smart to use your Tera on, since it conflicts with the ability and gets a more marginal gain; Skeledirge is an excellent user of different-type Tera for defensive purposes since Unaware combined with recovery and its slower bulky statline gives it a lot more mileage by avoiding SE hits; Quaquaval with Moxie and Aqua Step needs to punch one good hole and then starts trying to snowball, so it benefits from offensive Tera (be it same type nuking or a Surprise Coverage power up).
The approach also just feels more purposeful than the Galarian Starters. Their GMAX moves were pretty generic nukes, and it's partially informed by my bias against DMAX being a "use this or you suck" part of the game rather than a tool in the box. I also find it funny that Cinderace was clearly meant to be the "favorite/popular" starter despite them giving Rillaboom easily the most VGC-relevant kit for Grassy Surge alone (given how often Groudon/Kyogre are dominant Restricteds and Earthquake as a prime Spread move goes, among other benefits).
