I’ve used PostGIS with a Flask (and some js) front end when I was working on my MSc. (Mapping deprivation and services by postcode) Worked amazingly well and was relatively easy to get used to once I read the O’Reilly PostGIS book to get used to the function calls. As with any data project; munging the data into a usable format was the biggest hassle. Edit: used google maps for the display before they changed their licence. Haven’t updated to OSM yet...

Same. I use Flask because it's one of the lightest frameworks I could find. GeoJSON can be generated on the fly by PostGIS with very good performance. So Flask is just used as middleware to submit the query from URL params to PostgreSQL. For the front-end I usually use Leaflet with Mapbox (raster) tiles. I should switch to vector tiles but "@2x" raster tiles look good enough on HiDPI/Retina displays. I'm also an heavy QGIS user. I've managed to convince IT to put it in our internal Software Center so users can install it in one click without needing to be admin. It's becoming quite successful internally ;-). Take this Esri! However we still pay hundreds of k€ to Esri and nothing to QGIS. I've personnally donated a few euros but it's a really small amount compared to what we pay to Esri.
