All the libraries can render the tiles with minimal code.
Mapbox GL JS v2 seems the smoothest for pan and zoom, followed closely by MapLibre.
Over-zooming in Leaflet does not work as expected when using the L.canvas renderer.
I was unable to add a highlight effect or feature query with the Esri API. In the example, feature data is extracted by tilequery.
