You can't. Google does not let developers to control the amount of POIs being shown, and does not let developers download POI sets. Furthermore, each GMaps user will see more or less POIs depending on their own search history.
(And this is your periodic reminder that using GMaps' tiles goes against Big G's terms of service; and that's why GoogleMutant ...
Yes, it is. EPSG 4326 is the identifier for the World Geodetic System 84 (WGS84). If you check the Well Known Text (WKT) for WGS84 you will see it uses degrees as units:
EPSG 4326 is a coordinate system. Its units are degrees of latitude and longitude. If you define the lat/long of a point, then you know where that point is. There's nothing wrong with using EPSG 4326 for locating points.
You'll have accuracy problems if you try to calculate distance, area or angles in EPSG 4326, but that's not what you're doing. If you ...
Eventually, I was able to import the POIs into OSMAnd as GPX format. However, it was necessary to enable the GPX_USE_EXTENSIONS when exporting it in QGIS in order to allow OSMAnd to import the string attributes properly.
You have this project that uses OpenStreetMap - http://openpoimap.org/ https://wiki.openstreetmap.org/wiki/OpenPoiMap.
With overpass api https://wiki.openstreetmap.org/wiki/Overpass_API you can extract that info
