I have no dog in this race as far as Claude is concerned, but this is pushing a false dichotomy. Not using, say, WinForms or something, because it’s too limiting or because you don’t want to make a unique UI for every platform, doesn’t have to mean strapping an entire web browser to your frontend, there are plenty of other options.
The reason frameworks like Electron are popular is that we’ve spent a long time hammering a square peg into a round hole and there are now a whole bunch of tools for designing on top of web technologies and a lot of designers with experience with those tools. And of course, the fact that code can be reused between the web app and the desktop app helps too. But it does have a performance cost. The fact that you can have poorly performing and bloated native UIs too doesn’t change that no matter how well-optimised your HTML+CSS+JS is, you can create something of the same complexity that is faster and leaner using native widgets. And when people opt for the desktop app instead of web app, they typically want something that performs better than the web app.

Early Persona 5 is pretty rich in set pieces as it slowly introduces its many systems, but it does open up quite a lot after a while. It’s a content-rich 100+ hour long game, it kind of has to. It still has a lot of cutscenes even after that, but they’re mostly of the gamey yapping portraits kind, with cinematic cutscenes and anime FMVs left for climactic moments.
Persona 3 and 4 are similar in style, though not quite as cinematic, and you get to the meat of the games faster.
Persona 1 and 2 are completely different beasts, and what you dislike about Persona 5 so far will have no bearing on whether you’ll like those. The most modern versions are on PSP, however.
As for other JRPGs on Switch, from the same developer there’s Shin Megami Tensei V and the remaster of III. Even though they’re also from Atlus, they very much go in the opposite direction of Persona and are very stoic games where it’s mostly just you, the environment and the systems, and cutscenes are far and between.
Someone else mentioned the Trails games and I’ll second that. Like the Persona, they’re very story-rich, but not as budget-rich as Persona 5, which puts constraints on how that story is told. Also, if you like action RPGs, from the same developer (Falcom) there’s the Ys games. Ys: The Oath in Felghana is pretty much the pinnacle of the genre and is pretty short, so it’s a good snack between bigger games.
