Publishers forcing padding is real, but honestly some of the tightest recent series come from indie or smaller press stuff where there's no corporate pressure at all - check out things like Gideon the Ninth (which wraps up its core story nicely while leaving room for spinoffs) or even some of the newer grimdark fantasy that's designed as planned trilogies.
The Sanderson point stands, but I'd also say don't sleep on authors who actually finish their series instead of letting them peter out - look at completion dates, not just hype.
If you're willing to go slightly older (like 2023-2024 range), there's solid stuff out there, but newer releases sometimes are still mid-series so it's harder to vouch for the pacing yet.
