Mainly Vue. It's OK and pretty widely used, which gets you decent library support and such. If I were starting from scratch and didn't have organizational/team inertia & experience to consider, I'd probably give things like htmx a hard look.

I'd have to re-evaluate the current Android landscape because it's been a while, but I might still consider React Native only for that platform, because having RN smooth the rough edges off Android dev made it a lot more pleasant and quick, with far less time lost fighting the platform and working around/replacing bad 1st party stuff piecemeal. But maybe it's gotten better-enough in the last 4ish years that it's no longer tempting to drag in RN just to avoid native Android dev.

In general though, I just no longer default to advocating React for highly-interactive sites or "webapps", as I did for a while.
