SmartTube is good for this. It needs to be installed by the APK and updated manually but that’s the only friction I’ve encountered. Been using for around a year I’d say.

It even has SponsorBlock built in, so it can be configured to skip things like intros, recaps, or sponsor segments.

I looked at that before. It doesn't have voice search out of the box. You have to uninstall Youtube, root the device and fiddle with adb, to install some bridge application or something.

It could be a good reason to switch to Google's Android box device (Chromecast with Google TV) where this is supposedly simpler.
